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`.
Even if the interrupt pin is not initialized here because the callback function parameter `cb` is NULL, the device interrupts are configured here so that they will work when the interrupt pin is initialized later, as is the case when the Touch Device API is used, for example. Since the interrupt state is cleared on each read, this is not a problem even if the interrupt pin is not used at all.
Some of the `static inline` functions are only used in some
configurations, depending on the preprocessor. Explicitly disable the
warning to allow compilation with clang.
19816: drivers/lcd: code deduplication for st7735 and ili9341 r=aabadie a=gschorcht
### Contribution description
In preparation for the parallel interface support the following changes were made:
1. The code for basic communication (acquire/release SPI device, SPI transfers), which were always duplicated by copy & paste in each display driver again and again, has been moved to the LCD driver as low-level functions that are now used by the display drivers. These low level function allow
- code deduplication and
- to define a more abstract communication interface that can then be extended later by parallel communication interface
2. Identical GPIO initializations has also been moved from display drivers to the LCD driver.
3. Using a default implementation of `lcd_set_area` function allows further code deduplication.
Finally, the `ili9341` and `st7735` drivers only implement the inialization sequence for the LCD driver IC.
### Testing procedure
`tests/drivers/ili9341` should still work for a board with an ILI9341. Tested with `esp32-wrover-kit`.
`tests/drivers/st7735` should still work for a board with a ST77xx. Tested with `esp32s3-usb-otg`.

19777: cpu/avr8_common: Prepare for rework ISR r=benpicco a=nandojve
### Contribution description
This prepares for rework how ISR is handled for AVR-8 platform. It is not expected changes on the behavior but tests on other boards were welcome to avoid regressions.
#### Improvements
* Split UART state from ISR states. Now it is necessary two variables and GPIORx registers are automatically selected when available.
* UART states now supports up to 8 UARTs.
* Added AVR8_ISR macro do clean-up and hide internals related to ISR processing. This allows changes on ISR without any other changes on drivers.
### Testing procedure
Tests were conducted using atmega328p-xplained-mini and atxmega-a1u-xpro and the zigduino board was only built. The example thread_duel was used to test regressions.

19781: cpu/nrf{53,9160}: add pwm support r=benpicco a=dylad
### Contribution description
This PR moves the nRF52 PWM driver to `cpu/nrf5x_common` to allow nRF9160 and nRF53 to use this driver.
IP is identical on these families.
I didn't test on nRF9160DK and I didn't test if there is any regression on nRF52-based board as I don't have any so tests are welcome !
However it works fine on nRF53-based board.
### Testing procedure
Flash the `tests/periph/pwm` test application on `nrf5340dk` or `nrf9160dk`.
You can then use the `osci` command to make the onboard LEDs "breath".
You can also attach an oscilloscope and/or logic analyzer to watch the signal.

is provided for backward compatibility
- Move all info from `arduino_board.h` into the new file as trivial

same information, just in a different format
- a generic `arduino_board.h` is provided instead that just
uses the info in `arduinio_iomap.h` and provides them in the
format the code in `sys/arduino` expects it
- Add fine grained features to indicate for mappings
- availability of mappings for analog pins, DAC pins, PWM pins,
UART devices, SPI/I2C buses to the corresponding RIOT
identification can now be expressed:
- `arduino_pins`: `ARDUINO_PIN_0` etc. are available
- `arduino_analog`: `ARDUINO_A0` etc. are available

- `arduino_spi`: `ARDUINO_SPI_ISP` or similar are available
- `arduino_i2c`: `ARDUINO_I2C_UNO` or similar are available

can now be expressed as features:
- `aruino_shield_nano`: Arduino NANO compatible headers
- `aruino_shield_uno`: Arduino UNO compatible headers
- `aruino_shield_mega`: Arduino MEGA compatible headers
- `aruino_shield_isp`: ISP header is available
This provides the groundwork to implement shield support as modules
that can rely on the I/O mappings, rather than having to provide a
configuration per board.
19718: drivers/dht: busy wait reimplementation r=benpicco a=hugueslarrive
### Contribution description
In PR #19674, I also provided quick and dirty fixes to restore functionality on esp8266 and enable operation on AVR. While reviewing PR #18591, it became apparent to me that this driver needed a refresh, particularly its migration to ztimer.
The cause of the malfunction on esp8266 was that since the default switch to ztimer as the backend for xtimer, XTIMER_BACKOFF was no longer taken into account. Therefore, the correction I provided in PR #19674 simply made explicit what was previously done implicitly with xtimer and now needs to be done explicitly with ztimer (spinning instead of sleeping).
Moreover, it was unnecessarily complex to measure the pulse duration in a busy-wait implementation, which required 2 calls to ztimer_now() and 32-bit operations expensive on 8-bit architecture. Instead, it is sufficient to read the state of the bus at the threshold moment.
Finally, in practice, it is possible to reduce the read interval (down to less than 0.5s for DHT22) by "harassing" the DHT with start signals until it responds.
This re-implementation brings the following improvements:
- Many backports from `@maribu's` IRQ based implementation (#18591):
- Use of ztimer
- Use of errno.h
- Use of a dht_data structure to pass arguments, to facilitate integration
- Adaptation of the bit parsing technique to parse bits into the data array
- Reintroduction of DHT11/DHT22 differentiation.
- Separation of `dht_read()` steps into functions for better readability and the ability to share certain functions among different implementations
- Sensor presence check in `dht_init()`
- ~~Automatic adjustment to a minimum data hold time~~
- Default input mode changed to open drain (a pull-up resistor should be placed close to the output if necessary but not close to the input)
- AVR support without platform-specific handling by avoiding ztimer_spin() and using the overflow of an 8-bit variable as a pre-timeout to minimize time-consuming ztimer_now() calls
Regarding the changes in the start signal sequence and the removal of the `_reset()` function:
~~In the previous implementation, there was an unnecessary spike at the beginning of the signal sequence, corresponding to START_HIGH_TIME. This spike has been removed in the re-implementation, as it is unnecessary. Instead, the MCU now simply pulls the signal low for START_LOW_TIME and then releases the bus, which is sufficient for initiating communication with the DHT sensor.~~ Actually, it is necessary to raise the bus level; otherwise, the _wait_for_level() called immediately after to check the response of the DHT may read the port before the signal level is raised, resulting in a false positive.
Additionally, the previous implementation had an issue where the MCU switched back to output mode and went high immediately after reading the 40 bits of data. However, the DHT sensor was still transmitting 2 or 3 additional bytes of '0' at that point, causing a conflict. This issue has been resolved in the re-implementation:
~~Regarding the optimization for AVR, I have performed measurements of `_wait_for_level()` until timeout (85 loops):~~
~~- on esp8266-esp-12x: 264 µs, which is 3.11 µs per loop~~
~~- on nucleo-f303k8: 319 µs, which is 3.75 µs per loop~~
~~- on arduino-nano: 3608 µs, which is 42.45 µs per loop~~
~~Duration measurements on the Arduino Nano:~~

The I2C peripheral's shortcuts are used with the read and write register to automatically stop the I2C transaction or to continue with the next stage.
With simple I2C read and write bytes these shorts are not used, but are also not cleared by the function in all cases, causing it to use the shortcut configuration set by a previous function call. This patch ensures that the shorts are always set by the read and write functions
### Testing procedure
Should be possible to spot with a logic analyzer and the I2C periph test. Maybe the HIL test can also detect it :)

This patch releases the SPI bus when the memory devices is not found.
This frees the bus for other devices to use the bus. It also allows
future attempts to init the device.
The lowest possible value is `LORA_SF5` and not `LORA_SF6`. This fixes
the argument validation to allow setting `LORA_SF5` as spreading factor.

### Contribution description
This PR is a very small fix of inconsistent peripheral driver entry in `Kconfig` for `periph/timer`.
In Kconfig menu `(Top) → Drivers → Peripherals drivers` all entries start with the peripheral name in alphabetical order with only one exception, the timer entry. This entry is called `Configure timer peripheral driver`:
```
[ ] CPU unique ID
[ ] EEPROM peripheral driver
[ ] Flashpage peripheral driver ----
[*] GPIO peripheral driver --->
[ ] HWRNG peripheral driver
[ ] PWM peripheral driver
[*] Power Management (PM) peripheral driver
[*] Auto initialize Power Management (PM) peripheral
[ ] Quadrature Decoder (QDEC) peripheral driver
[ ] RTC peripheral driver ----
[ ] SPI peripheral driver ----
[*] UART peripheral driver --->
[*] Configure timer peripheral driver --->
```

1. changes the entry to `Timer peripheral driver` and
2. corrects the alphabetical order.

The `mtd_default` module defines `MTD_NUMOF` if not existing based on the `MTD_*` defines which are usually set to the corresponding MTD device pointer variables `mtd*`. However, these MTD device pointer variables are not always made known by external variable declarations. An example are SD Card Interfaces which are defined via the `mtd_sdcard_default` module. As a consequence, an application that uses `mtd_default` has still to be modified. Therefore, `mtd_default` also declares up to 6 `mtd*` MTD device pointer variables.

### Contribution description
This PR provides a small cleanup:
- the copy of `sdcard_spi_params_t` is removed (commit bfc2a51f70)
- the documentation was changed to fit the 100 characters per line. (commit 36f0162b34)
It is not necessary to hold a complete copy `sdcard_spi_params_t` in the device descriptor. Constant parameters can be used directly from ROM instead. This saves 24 bytes of RAM.
### Testing procedure

After changing IN EPs also to use XFRC (Transfer Complete) interrupts in non-DMA mode, the TXFE (TX FIFO Empty) interrupt is no longer needed to signal the completion of an IN transfer.
XFRC (Transfer Complete) interrupts are now also used for OUT EPs in non-DMA mode. RXFLVL (RX FIFO Level) interrupts are no longer used to signal completed transfers, but only to copy data from FIFO to memory and to set a flag indicating that a SETUP stage is in progress. STUP (SETUP phase done) interrupts are then used to signal a completed SETUP stage and to reset the flags that indicates the SETUP stage. The flag that indicates the SETUP stage in progress is used to ignore additional XFRC interrupts for EP0 during the SETUP stage.
XFRC (Transfer Complete) interrupts are now also used for IN EPs in non-DMA mode. TXFE (TX FIFO Empty) interrupts are not necessarily needed but are still enabled.
The USB device driver ISR sets a thread flag of the waiting USBUS thread to indicate that it has to handle a USB device driver event. However, setting a thread flag only sets `sched_context_switch_request` to indicate that a thread context switch would be required, but it is not executed. Therefore, for STM32 MCUs, `cortexm_isr_end` was called to execute the context switch. Since the driver is also used by other platforms, this call is replaced by a direct call of `thread_yield_higher` if required. NOTE: For ESP32x SoC, such a thread context switch is implicitly executed at the end of each ISR if necessary.
If the MCU/board has only an USB OTG FS peripheral or only an USB OTG HS peripheral, it should only need to specify the USB OTG FS definitions such as the number of EPs or the FIFO sizes or only the USB OTG HS definitions. This commit cleans up the code so that it is translatable without the respective definitions.
The address in the USB device can be set either directly after the SETUP stage on receipt of the `SET ADDRESS Request` or after the associated status stage. When the USB device address has to be set depends on the hardware. If `USBDEV_SET_ADDR_AFTER_STATUS` has the value 1 (default), the address is only set in the USB device after the status stage. Overwrite it with 0 in `periph_cpu.h` to set the address already directly after the SETUP stage.

This PR fixes the DMA mode for all STM32 USB OTG HS cores (including that for STM32F4xx CID 1.xxx) and reenables it. It fixes remaining problems in issue #19359.
This PR includes also includes some changes that are needed to use the DMA mode:
- EP number is used as defined in CMSIS (if defined) for STM32
- `periph_usbdev_hs` feature is added in Kconfig
- `periph_usbdev_hs` feature is added in board definition of `stm32f429i-disc1`
- largest number of available EPs is used for STM32 instead of the smallest number (to be able to use all EPs of HS peripheral)
- `stm32f429i-disco` is removed from blacklist in `tests/usbus_cdc_ecm` since it uses the HS peripheral
### Testing procedure
The following tests should work
```python
USEMODULE=stdio_cdc_acm BOARD=stm32f429i-disc1 make -j8 -C tests/usbus_cdc_ecm flash
```

19416: cpu/rpx0xx/cmsis: Update vendor header files r=benpicco a=maribu
### Contribution description
Generated new vendor header files from upstream SVD files using:
./SVDConv "$PICO_SDK_DIR"/src/rp2040/hardware_regs/rp2040.svd \
--generate=header --fields=macro --fields=enum
Note: The missing `--fields=struct` flag resulted in the header no longer containing bit-fields to represent different fields within registers. While this would generally ease writing code, the RP2040 has the unpleasant feature of corrupting the remaining bits of the register when a write access that is not word-sized occurs in the memory mapped I/O area. This could happen e.g. when a bit field is byte-sized and byte-aligned.
### Testing procedure
No binary changes (hopefully).
### Issues/PRs references
This adds a few additional vendor defines, notably for USB. If anyone were to implement USB, this would be a requirement.
19418: cpu/gd32v: fix gpio_read in periph_gpio r=benpicco a=gschorcht
### Contribution description
This PR fixes a bug in `gpio_read` which made `gpio_read` completely unusable!
A small bug with big consequences. In `gpio_read` the combined port | pin_num parameter `pin` was used instead of the pin number `pin_num` for the call of `_pin_is_input`. This caused the problem that for example instead of accessing GPIOA->CTL0 with address 0x40010800, address 0x60018c00 was accessed. As a result, a pin was randomly detected as input or output and thus a result was arbitrarily returned. Approx. 50% of all inputs always returned LOW.
I found this error by coincidence when I tried to find out why the BOOT0 button on a Sipeed Longan Nano is not usable as a button in RIOT.
### Testing procedure
Flash `tests/periph_gpio`
```
BOARD=sipeed-longan-nano make -j8 -C tests/periph_gpio flash
```
and use commands
```
init_in 0 8
read 0 8
```
Without this PR, the pin is always LOW. With the PR, the pin should be HIGH when the BOOT button is pressed.

DMA mode is disabled for now due to several problems:
- The STALL bit of the OUT control endpoint does not seem to be cleared automatically on the next SETUP received. At least the USB OTG HS core does not generate an interrupt on the next SETUP received. This happens, for example, when CDC ACM is used and the host sends the SET_LINE_CODING request. In this case the enumeration of further interfaces, for example CDC ECM is stopped.
- The Enumeration fails for CDC ECM interface which uses URB support.
This commit fixes the problem that the driver uses the wrong number of EPs when using the USB OTG HS core. The reason is that the constant `DWC2_USB_OTG_FS_NUM_EP` is used in several places even though there is a function `_max_endpoints` which takes into account the configuration used. For most MCUs this is not a problem, because they have only a USB OTG FS core anyway. But for MCUs like the STM32, which has both a USB OTG FS core and a USB OTG HS core, it matters.
17086: usbdev: Add dedicated stall functions r=benpicco a=bergzand
### Contribution description
This PR adds dedicated stall functions for usbdev peripherals. Two
functions are added. The first function (usbdev_ep_stall) to enable and
disable the stall condition on generic endpoints. The second function is
a dedicated function to set the stall condition on endpoint zero in both
directions. This status can only be set and should automatically be
cleared by the usbdev implementation (or hardware) after a new setup
request is received from the host.
### Testing procedure
- examples/usbus_minimal should still enumerate correctly on the host side.
- #17085 can be used to demonstrate the ep0_stall function with the `tests/usbus_cdc_acm_stdio/` test

19358: sys/usbus/cdc/ecm: fix High-Speed mode r=dylad a=gschorcht
### Contribution description
This PR provides some changes to fix the USBUS CDC ECM interface in High-Speed mode.
In High-Speed mode, the EP data size has to be at least 512 bytes instead of 64 Byte in Full-Speed mode. To be able to define configurations like EP data sizes depending on whether Full-Speed or High-Speed USB device peripherals are used, the feature `periph_usbdev_hs`/`HAD_PERIPH_USBDEV_HS` is introduced.
### Testing procedure
Use `tests/usbus_cdc_ecm` and any board with USB HS connector, for example:
```
USEMODULE=periph_usbdev_hs_utmi BOARD=stm32f723e-disco make -j8 -C tests/usbus_cdc_ecm flash
```
`ping` command works with this PR but doesn't work without this PR.

19292: sys/phydat: Fix unit confusion r=miri64 a=maribu
### Contribution description
Previously, `UNIT_G` was used for g-force with the correct symbol `g`, `UNIT_GR` for gram (as in kilogram) with the incorrect symbol `G` (which would be correct for Gauss), and `UNIT_GS` for Gauss with symbol `Gs` (which is an alternative correct symbol).
To avoid confusion between G-Force, Gauss, and Gram the units have been renamed to `UNIT_G_FORCE`, `UNIT_GRAM`, and `UNIT_GAUSS`. In addition, gram now uses the correct symbol `g`; which sadly is the same as for g-force. But usually there is enough context to tell them apart.

18392: drivers/servo: reimplement with high level interface r=benpicco a=maribu
### Contribution description
The previous servo driver didn't provide any benefit over using PWM directly, as users controlled the servo in terms of PWM duty cycles. This changes the interface to provide a high level interface that abstracts the gory PWM details.
In addition, a SAUL layer and auto-initialization is provided.
### Testing procedure
The test application provides access to the servo driver via the `saul` shell command.

Each write resulted in the MG90S servo that I connected to move to the corresponding position.

19271: core/xfa: disable asan on llvm r=benpicco a=Teufelchen1
### Contribution description
Hi! 🦎
When using llvm and address sanitation, the XFA trip the sanitizer.
This PR attempts to fix this by adding the `no_sanitize` attribute to the XFA macros. Sadly, this attribute is not known by gnu, a guard is hence needed. I'm open for alternatives as I dislike this solution but it is the best I could come up with.
### Testing procedure
Before this patch:
Go to `examples/gnrc_minimal` and run `TOOLCHAIN=llvm make all-asan` and then `make term`.
You should see an error similar to this:
```
==3374719==ERROR: AddressSanitizer: global-buffer-overflow on address 0x080774e0 at pc 0x0804af5e bp 0x0808eb88 sp 0x0808eb78

19243: cpu/gd32v: add periph_gpio_ll and periph_gpio_ll_irq support r=benpicco a=gschorcht
### Contribution description
This PR provides the `periph_gpio_ll` and `periph_gpio_ll_irq` support for GD32VF103. Level triggered interrupts are emulated.
`periph_gpio_ll_irq` could be split off from this PR as a separate PR if necessary.
### Testing procedure
Use any GD32V board and connect PA0 -> PB0 and PA1 -> PB1 where PA is the output port and PB the input port. With these connections `tests/periph_gpio_ll` should work.
```
BOARD=sipeed-longan-nano make -j8 -C tests/periph_gpio_ll flash term
```
If necessary, change the input and output pins by setting the environment variables and connect the corresponding pins, for example for `seeedstudio-gd32` PA1 -> PB8 and PA8 -> PB9:
```
PIN_OUT_0=1 PIN_OUT_1=8 PIN_IN_0=8 PIN_IN_1=9 BOARD=seedstudio-gd32 make -j8 -C tests/periph_gpio_ll flash term
