Note that for the very CPU this driver is used with (nRF52 on the
microbit-v2 board), this currently needs extra workarounds to copy
written data from flash to RAM so that the driver can see it. (Otherwise
it silently writes 00, and then correctly reads 00 from the bus all the
time).
This adds the features

The documentation on the state `GPIO_DISCONNECT` was a bit vague. The
API doc said it should disconnect the GPIO from all peripherals, the
test also tested them for being electrically disconnected.
The documentation in both the test and the API is extended to point out
that a GPIO indeed SHOULD be in high impedance state, but that user
MUST NOT expect that this requested is honored by every implementation
and for every GPIO pin.
In the test it is also pointed out that failing the test for a GPIO
in the `GPIO_DISCONNECT` state being electrically disconnected is for
some pins expected, and that the test should be just run again with
different GPIOs. The test intentionally tests for a feature not provided
by every GPIO pin rather than warning on a failure: The effort to just
flash and run the test again with different GPIOs is relatively low, but
it does confirm correct behavior of the API.
This commit optimizes the `gpio_conf_t` type in the following
regards:
- The "base" `gpio_conf_t` is stripped from members that only some
platforms support, e.g. drive strength, slew rate, and disabling of
the Schmitt Trigger are no longer universally available but
platform-specific extensions
- The `gpio_conf_t` is now crammed into a bit-field that is 8 bit or
16 bit wide. This allows for storing lots of them e.g. in
`driver_foo_params_t` or `uart_conf_t` etc.
- A `union` of the `struct` with bit-field members and a `bits` is used
to allow accessing all bits in a simple C statement and to ensure
alignment for efficient handling of the type

Parameter `num` of `mtd_write_page_raw` is the number of bytes to be written, which is the number of sectors to be written`count` multiplied by the pages per sector `mtd->pages_per_sector` and the page size `mtd->page_size`.
Assertions are used instead of returning a NULL pointer to detect errors in the MTD definition and access in the case that the return value is not evaluated.
Allow accessing supported timer frequencies with a dedicated API.
This API needs to be implemented per platform and is available with
the feature periph_timer_query_freqs.
This makes it easier to use common error reporting such as `strerror()`
or `tiny_strerror()` to give more insight on why something failed.
The custom error codes via `enum` have been updated to be synonymous
with the `errno` codes for backward compatibility.
In addition, `pcf857x_init()` has been updated to no longer or
together the return code, but rather abort on the first fail transaction
and return the error code as is. Otherwise (when both fail due to
different error codes) the returned error code may be garbage.
19465: drivers/mtd: use XFA for pointers to defined MTDs r=benpicco a=gschorcht
### Contribution description
This PR provides the support to hold pointers to defined MTDs within a XFA. The XFA allows
- to access MTDs of different types (`mtd_flashpage`, `mtd_sdcard`, `mtd_emulated`, ...) by an index
- to determine the number of MTDs defined in the system.
### Testing procedure
To be defined once PR #19443 is merged because emulated MTDs will allow to test this PR on arbitrary boards.
### Porting Guide
For external boards:
- remove the `MTD_NUMOF` definition from `board.h`
- add `MTD_XFA_ADD(<mtd_dev>, <idx>);` to the definition of `<mtd_dev>`.
- `MTD_0`, `MTD_1`, … defines are no longer needed.

19981: Fletcher32: Add incremental API r=benpicco a=bergzand
### Contribution description
This PR extends the current fletcher32 checksum with an incremental API mode. This way the bytes to be checksummed can be supplied via multiple successive calls and do not have to be provided in a single consecutive buffer.
I've also rephrased the warning with the original function a bit as that function uses an `unaligned_get_u16` to access the data. The data thus does not require alignment, but the length does need to be supplied as number of 16 bit words.

### Contribution description
The PR extends the LCD driver by a low-level interface for MCU-driven implementations of the MCU 8080 16-/8-bit parallel interface, allowing the MCU to use special peripherals for the interface, such as the FMC for STM32 MCUs, which is significantly faster than the integrated GPIO-driven parallel interface implementation of the LCD driver.

19956: cpu/esp32: fix heap definition for ESP32-S2 and ESP32-S3 r=benpicco a=gschorcht
### Contribution description
For ESP32-S2 and ESP32-S3 the symbol `_heap_end` must not be used as `_eheap` for the newlibc `malloc` and function `sbrk`.
`_heap_end` is used by the ESP-IDF heap implementation `esp-idf-heap` and points to the highest possible address (0x40000000) that could be used for the heap in ESP-IDF. It doesn't point to the top address of the unused SRAM area that can be used in newlibc `malloc` and function `sbrk`. Instead, the origin and the length of `dram0_0_seg` must be used to calculate the end of the heap `_eheap`.
The problem only occurs for the newlibc `malloc` when the `sbrk` function is used but not for the ESP-IDF heap implementation `esp_idf_heap`.
### Testing procedure
Use any ESP32-S2 or ESP32-S3 board and flash `tests/sys/malloc`, e.g.
```
CFLAGS='-DCHUNK_SIZE=16384' USEMODULE='stdio_uart' BOARD=esp32s3-pros3 make -j8 -C tests/sys/malloc flash
```
Without the PR the `nm` command will give the wrong address
```
nm -s tests/sys/malloc/bin/esp32s3-pros3/tests_malloc.elf | grep _eheap
40000000 A _eheap
```
The test will stuck, i.e. the allocation of memory stops when the top of unused SRAM is reached and the board restarts when the watchdog timer expires. With the PR it should work as expected

19957: cpu/esp32: fix Octal SPI RAM for ESP32-S3 r=benpicco a=gschorcht
### Contribution description
This PR fixes Octal SPI RAM handling for ESP32-S3.
Functions that are used during the initialization of the Octal SPI RAM must reside in IRAM instead of Flash. Otherwise, the system stucks during boot once the Octal SPI RAM is enabled. The reason is that the Flash is not available during the initialization of the Octal SPI RAM and the functions that are called during that initialization can't be accessed in Flash. As a result the call of such a function leads to code that is messed up and the system crashes.
The PR also includes the documentation fixe for the `esp32s3-box`. It also includes a small documentation fix regarding the SPI RAM for the `esp32s3-pros3` board.
### Testing procedure
Use a board that has Octal SPI RAM and flash `tests/sys/malloc`, e.g.:
```
CFLAGS='-DCHUNK_SIZE=16384' USEMODULE='stdio_uart esp_spi_ram esp_log_startup' \
BOARD=esp32s3-box make -C tests/sys/malloc

19915: drivers/lcd: support MCU 8080 8-bit parallel mode r=benpicco a=gschorcht
### Contribution description
LCD driver ICs usually support
- SPI serial mode,
- MCU 8080 8-bit parallel mode and
- MCU 8080 16-bit parallel mode.
This PR extends the LCD display driver API to support the MCU 8080 8-/16-bit parallel modes and implements a GPIO-driven MCU 8080 8-bit parallel mode.
The following features are already working locally and will be provided as follow-on PRs for which this PR is a prerequisite.
- GPIO-driven bit-banging implementation of the 16-bit mode of the MCU 8080 parallel interface
- Enabling the display on `stm32f723e-disco` and `stm32l496g-disco` using the feature above
- Definition of a low-level API for the parallel modes using the LCD controller of the MCU
- Using FMC for the display on `stm32f723e-disco` and `stm32l496g-disco`
- Using LCD controller for the display of `esp32-wt32-sc01-plus` (PR #19917)
### Testing procedure
The PR can be tested with PR #19917 on top of this PR.
```
BOARD=esp32s3-wt32-sc01-plus make -j8 -C tests/drivers/st77xx flash
```
The following video shows the test.
**Please note** The test is pretty slow because the display has 480 x 320 pixels and the MCU 8080 8-bit parallel interface is realized by a GPIO-driven bit-banging implementation where each GPIO of the data bus is set separately. A follow-up PR will use the ESP32-S3 LCD controller and DMA for this board. This PR just defines the extension of the driver by the parallel interface and provides the bit-banging implementation for MCUs that don't have a LCD controller on chip.

19919: drivers/st77xx: introduce rotation defines r=benpicco a=gschorcht
### Contribution description
The PR introduces counterclockwise rotations for the definition of parameter `ST77XX_PARAM_ROTATION`.
It is more intuitive and universal to use `ST77XX_ROTATION_{0,90,180,270}` instead of `ST77XX_ROTATION_{ST77XX_ROTATION_{VERT,VERT_FLIP,HORZ,HORZ_FLIP}`, especially because the orientation of the display may vary with respect to the orientation of the board.
### Testing procedure
`tests/drivers/st77xx` should still work, for example:

For the parallel interface support the following changes were made:
1. Additional `lcd_*` pseudomodules are defined to control whether SPI serial or MCU 8080 8-/16-bit parallel interface is used.
2. The low level function implementation was extended for parallel interfaces so that the now can use either the SPI serial interface or the MCU 8080 8-/16-bit parallel interface.
Using the `lcc_*` modules, either the SPI serial interface or the MCU 8080 8-/16-bit interface or even both for multiple display can be used simultaneously.
This allows including the header without using the module. Obviously,
calls to the functions provided by the header won't like without using
the module. But including the header can still be useful for e.g.:
if (IS_USED(MODULE_PCF857x)) {
/* make use of the module */
}
In the above example all calls to pcf857x functions would be optimized
out when the module is not used, full compile checks happen in either
case.
19825: drivers: rename st7735 to more generic st77xx r=aabadie a=gschorcht
### Contribution description
This PR provides the following changes:
- renames the driver `st7735` to `st77xx`
- renames the test `st7735` to `st77xx`
- models controller variants as pseudomodules `st7735`, `st7789` and `st7796`
- removes the buggy initialization as a workaround to use reset defaults, see issue #19818
- adds backward compatibility header files for `ST7735_PARAM_*` symbols
- adds a test board for compilation test of backward compatibility
- updates the corresponding board definitions
The PR should solve the remaining dependency issues in KConfig we had by using `st7735` module for different controller variants. The backward compatibility header files should work for boards that still use `ST7735_PARAM_*` in their board definitions so that the board defintions at user's side use shouldn't be affected.
~To be compilable, the PR includes PR #19824.~
### Testing procedure
- Green CI
- `tests/drivers/disp_dev` and `tests/drivers/st77xx` should still work for all boards using a ST77xx display.
- The PR was already tested for these tests for:
- [x] `adafruit-pybadge`
- [x] `esp32s2-lilygo-ttgo-t8`
- [x] `esp32s3-usb-otg`

If a board definition already used the ST7735 driver, `st7735*.h` header files and `ST7735_*` macros were used in the board definitions to define the default configuration parameter set. For backward compatibility these header files are kept and the `ST7735_*` macros are mapped to the `ST77XX_*` macros if they are defined.

### Contribution description
To obtain coordinates from the touch panel that correspond to the display coordinates, it is often necessary to convert the coordinates by swapping and mirroring. Instead of hard coding this conversion, it is now controlled by an additional conversion parameter. For the sake of simplicity, possible rotations are predefined.
The PR fixes `tests/pkg/lgvl_touch` for the `stm32f429i-disc1` board where the coordinates from the touch panel seem to be mirrored in relation to the screen coordinates at the vertical axis.
### Testing procedure
Flash `tests/pkg/lvgl_touch`. Without this PR the coordinates of the button don't correspond to the touch panel coordinates once the button has been pressed. Instead they seem to be mirrored at the vertical axis. With this PR, the coordinates should be correct.

19884: drivers/touch_dev_gestures: add gesture recognition for touch devices r=aabadie a=gschorcht
### Contribution description
This PR adds simple gesture recognition for touch devices accessed via the generic Touch Device API. It can be used in conjunction with device drivers that use either interrupts or polling mode. It supports up to two touches and the following gestures:
- Single and double tap at given position
- Long press and release given position
- Moving while pressed with current position
- Swipe left, right, up and down
- Zoom in (spread) and out (pinch)
Gesture recognition has been tested with:
- [x] `stm32f746g-disco` (works out of the box)
- [x] `stm32f723e-disco` (works out of the box)
- [x] `stm32f429i-disc1` (works on top of PR #19885)
- [x] `stm32l496g-disco` (works with my local LCD display changes waiting for PR #19825, not yet provided)
- [x] `esp32s3-wt32-sc01-plus` (new board, not yet provided)
### Testing procedure
Flash `tests/drivers/touch_dev_gestures` to a board with touch pane, for example:
```
BOARD=stm32f746g-disco make -j8 -C tests/drivers/touch_dev_gestures/ flash
```
PR #19885 is required for the `stm32f429i-disc1` board.

19885: drivers/stmpe811: changes for interrupt-driven touch handling and gesture recognition r=aabadie a=gschorcht
### Contribution description
This PR contains changes needed for the purely interrupt-driven handling of the touch position as `touch_dev` device, which is a prerequisite for the realization of gesture recognition. (PR #19884).
The interrupt-driven approach of `touch_dev` devices (PR #19882) and the gesture recognition (PR #19884) need continuous reporting of the touch position as long as there is at least one touch. Since the driver so far only uses the _Touch Detect_ interrupt, only the position at the beginning of a touch is available. All further positions must be polled.
Therefore, the changes in this PR additionally enable the _FIFO Threshold_ interrupt when the `touch_dev` module is enabled. However, since the _Touch Detect_ interrupt does not work reliably when the _FIFO Threshold_ interrupt is enabled and the FIFO Threshold is 1, the FIFO Threshold is set to 2 by default when the `touch_dev` module is enabled.
Furthermore, the FIFO queue has to be reset after reading one touch position. Otherwise new touch positions are processed with a delay if the rate of calling the function to read the FIFO is slower than the rate at which the FIFO is filled. The reason for this is that with each call of this function only the oldest touch position is read value by value from the FIFO. Gestures can't be implemented with such a behavior.
### Testing procedure
1. `tests/drivers/stmpe811` should work as before (only a single position is shown):

For continuous reporting of the touch position the FIFO threshold interrupt is used. This is necessary for example to implement gestures in interrupt mode. To activate the FIFO threshold interrupt and thus continuous reporting, the macro 'STMPE811_FIFO_THRESHOLD_ENABLED' must be set to 1. However, the driver only works reliably with FIFO threshold interrupts if the FIFO threshold value is at least 2. Otherwise the Touch Detect interrupt will not work correctly when a touch is released. Therefore, the FIFO threshold is set to 2 by default when `STMPE811_FIFO_THRESHOLD_ENABLED` is set. This default value can be overwritten by `STMPE811_FIFO_THRESHOLD`.
The FIFO queue has to be reset after reading one touch position. Otherwise new touch positions are processed with a delay if the rate of calling the function to read the FIFO is slower than the rate at which the FIFO is filled. The reason for this is that with each call of this function always only the oldest touch position is read value by value from the FIFO. Gestures, for example, can't be implemented with such a behavior
19880: drivers/ft5x06: fix initialization if callback function parameter is NULL r=aabadie a=gschorcht
### Contribution description
This PR fixes the `ft5x06` driver initialization if the callback function parameter `cb` is `NULL. This might be the case for example if the application uses the touch device in polling mode.
If the interrupt pin is initialized if the callback function parameter `cb` is `NULL`, the driver crashes the first time an interrupt is triggered. Therefore, the INT pin must be initialized only if also the callback function parameter `cb` is not `NULL`.
To be able to test the polling mode, this PR also includes a change of the `tests/drivers/ft5x06` application which introduces the environment variables `FT5X06_POLLING_MODE` `FT5X06_POLLING_PERIOD` and in the makefile.
### Testing procedure
1. Use any board with a FTXXXX touch device and test it in polling mode, for example:
```
FT5X06_POLLING_MODE=1 BOARD=stm32f746g-disco make -C tests/drivers/ft5x06 flash term
```
It should work as expected.
```

To obtain coordinates from the touch panel that correspond to the display coordinates, it is often necessary to convert the coordinates from the touch display by swapping and mirroring. For the sake of simplicity, possible rotations are additionally defined.
If the INT pin is initialized if the callback function parameter `cb` is `NULL`, the driver crashes the first time an interrupt is triggered. Therefore, the INT pin must be initialized only if also the callback function parameter `cb` is not `NULL`.

### Contribution description
Currently the buffer size on tinydtls is set in its Makefile whenever `gcoap` module is present. This limits the ability of the user to override the value. This adds a pre-check of the `CFLAGS` to see if it was set before.

Try setting `CFLAGS += -DDTLS_MAX_BUF=<some_value>` on `examples/gcoap_dtls`, you should be able to override the default value without errors.

19539: drivers/periph_sdmmc: define a High-level SDIO/SD/MMC API and low-level SDMMC periperal driver interface r=benpicco a=gschorcht
### Contribution description
This PR provides a SDIO/SD/MMC Device API (SDMMC). It implements a SD host controller driver that provides a high-level functions using a low-level SDIO/SD/MMC peripheral driver for accessing
- MultiMediaCards (MMC) and Embedded MultiMediaCards (eMMC)
- SD Memory Cards (SD Cards) with Standard Capacity (SDSC), High Capacity (SDHC) or Extended Capacity (SDXC).
It supports:
- 1-bit, 4-bit and 8-bit data bus width
- Default Speed and High Speed
- Auto-CLK
The SDIO/SD/MMC device API (SDMMC) is divided into two parts:
1. The high-level API that implements the SD Host Controller driver and allows
- to inititialize and identify different types of cards,
- to access them either blockwise or bytewise,
- to get information about the used card, and
- to send single commands or application specific commands to the card.
2. The low-level SDIO/SD/MMC peripheral driver implements the low-level functions required by the high-level device API. It has to be implemented for each MCU.
### Limitations:
- Only one card per SDIO/SD/MMC device is supported.
- eMMCs specific features are not supported.
- UHS-I, UHS-II and UHS-III are not supported.
### Testing procedure
PR #19540, PR #19760 or PR #19786 is needed to test this PR.

19860: drivers/ft5x06: fix vendor ID for FT6xx6 and FTxxxx register addresses r=benpicco a=gschorcht
### Contribution description
This PR provides a fix of the vendor ID for FT6xx6 touch panel driver ICs and a fix of register addresses for FTxxxx.
According to the [Application Note for FT6x06 CTPM](https://cdn-shop.adafruit.com/datasheets/FT6x06_AN_public_ver0.1.3.pdf), the vendor ID of FT6x06 touch panel driver ICs is `0x11` instead of `0xcd`. Although there are no information found in the Web about the FT6x36, the FT6336U touch panel of a ESP32-S3 WT32 SC01 Plus is also working with `0x11` as vendor ID so that it seems that FT6x36 is also using `0x11` as vendor ID.
Figured out with a `stm32f723e-disco` board (revision D03). Without this PR, `tests/drivers/ft5x06` gives:
```
+------------Initializing------------+
[ft5x06] init: invalid vendor ID: '0x11' (expected: 0xcd)

Some background information found in the Web:
- According to the [STM32CubeF7](c20e6dd15b/Drivers/BSP/STM32F723E-Discovery/stm32f723e_discovery_ts.c (L24-L27)) the FRIDA LCD panel mounted on the `stm32f723e-disco` board either uses FT6x36 (prior revision D) or FT3x67 (revision D). However, the FT5x06 driver type for the card is defined as FT6x06, which does not seem correct: bb9011c3fb/boards/stm32f723e-disco/include/board.h (L59)
- According to the [STM32CubeF7](c20e6dd15b/Drivers/BSP/Components/ft6x06/ft6x06.h (L269-L270)), the vendor ID for FT6x36 should be `0xcd`. However, the FT6336U on ESP32-S3 WT32 SC01 Plus works with vendor ID `0x11`.
- The [Adafruit FT6206 library](95118cd983/Adafruit_FT6206.h (L28)) uses `0x11` as vendor id.
- The `stm32l496g-disco` board uses a FT6236 which has vendor ID `0xcd`.
So the information available on the web is confusing. Maybe, a better solution would be to accept `0x11` as well as `0xcd` as vendor ID for FT6xxx touch panels. Unfortunately, there are no documents available on the registers directly from FocalTech 😟 so it seems to be more speculation than knowledge.

19886: cpu/efm32: fix DAC configuration r=benpicco a=gschorcht
### Contribution description
The EFM32 MCU allows the reference voltage to be configured per DAC device, not per DAC channel. Also, the DAC reference voltage was defined in the configuration but not used anywhere.
At the moment we have only defined one board (`stwstk6220a`) that uses the DAC, so changing the configuration interface shouldn't be critical.
### Testing procedure
`tests/periph/dac` should still work for the `stwstk6220a`
```
BOARD=slwstk6220a make -j8 -C tests/periph/dac flash
```
I don't have a `stwstk6220a` board (EFM32 Series 0) so that I can't test it. I could only test it for the `sltb009a` board (EFM32 Series 1) with the change for VDAC in PR #19887.
