19803: cpu/nrf5x_common: rework LFCLK source selection r=benpicco a=dylad
### Contribution description
This PR changes the source selection of LFCLK for all nRF families.
This idea is to use the values provided by Nordic vendor files to properly populate the source of the LFCLK. Then setup a per CPU check to ensure the value provided at board level is fine. In the end, the LFCLK source selection is a mere assignment.
The selection of the LFCLK source is still done at board level. I also add a bit of documentation to help users to select another value if needed.
I'll provide in a followup PR, `periph_rtt` support for both nRF9160 and nRF53.
### Testing procedure
CI should be enough I think. Otherwise, one can ran tests/periph/rtt on any nRF51-based board and any nRF52-based board.
You can also change the LFCLK source at board level to ensure the guards are doing their jobs.

19733: cpu/msp430: reorganize code r=maribu a=maribu
### Contribution description
RIOT supports two distinct families of the MSP430: The [MSP430 x1xx] MCU family and the [MSP430 F2xx/G2xx] MCU family. For both incompatible MCU families the code was located in the msp430fxyz folder, resulting in case of the UART driver in particularly bizarre code looking roughly like this:
```C
#ifndef UART_USE_USCI
/* implementation of x1xx peripheral ... */
#else
/* implementation of F2xx/G2xx peripheral ... */
#endif
/* zero shared code between both variants */
```
This moves peripheral drivers shared between the two families to msp430_common and splits the SPI and UART driver into two MCU families.
In addition, it cleans up the `msp430_regs.h` by dropping most of it and using the macros and symbols provided by the vendor header files. There is little reason for us to maintain constants when TI is already doing that.

19769: cpu/nrf53: add initial support with nRF5340DK-APP board r=maribu a=dylad
### Contribution description
This PR adds support for nRF5340 MCU and its associated Nordic development board, nRF5340DK.
This MCU provides a dual Cortex-M33, one application core running at up to 128MHz, and one network core running at up to 64MHz.
Peripherals are inherited from others Nordic MCUs families so it shouldn't be hard to add more of them in followup PRs.
For now, only the minimal set of peripherals is supported:
- GPIO / GPIO_IRQ
- UART
- TIMER
### Testing procedure
Build the usual test application for the supported peripherals and flash the board.
nRF5340DK provides two serial ports on its embedded debugger. RIOT's shell should be available on the first one (/dev/ttyACM0)

The correct macro name is `ARDUINO_I2C_UNO` for Arduino UNO compatible
I2C bus location, or `ARDUINO_I2C_NANO` for Arduino Nano compatible
I2C bus location.
- Rename all `arduino_pinmap.h` to `arduino_iomap.h`
- An empty `arduino_pinmap.h` that just includes `arduino_iomap.h`
is provided for backward compatibility
- Move all info from `arduino_board.h` into the new file as trivial
macros, so that they can also be used outside of sketches
- The new name reflects the fact not just pin mappings, but also
other I/O features such as PWMs are mapped
- Drop all `arduino_board.h`
- `arduino_board.h` and `arduino_iomap.h` now provide the exact
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_pwm`: `ARDUINO_PIN_13_PWM_DEV` etc. are available
- `arduino_dac`: `ARDUINO_DAC0` etc. are available
- `arduino_uart`: `ARDUINO_UART_D0D1` or similar are available
- `arduino_spi`: `ARDUINO_SPI_ISP` or similar are available
- `arduino_i2c`: `ARDUINO_I2C_UNO` or similar are available
- mechanical/electrical compatibility with specific form factors
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.
RIOT supports two distinct families of the MSP430: The [MSP430 x1xx]
MCU family and the [MSP430 F2xx/G2xx] MCU family. For both incompatible
MCU families the code was located in the msp430fxyz folder, resulting
in case of the UART driver in particularly bizarre code looking roughly
like this:
#ifndef UART_USE_USCI
/* implementation of x1xx peripheral ... */
#else
/* implementation of F2xx/G2xx peripheral ... */
#endif
/* zero shared code between both variants */
This splits the peripheral drivers for USCI and USART serial IP blocks
into separate files and relocates everything in cpu/msp430, similar to
how cpu/stm32 is organized.
[MSP430 x1xx]: https://www.ti.com/lit/ug/slau049f/slau049f.pdf
[MSP430 F2xx/G2xx]: https://www.ti.com/lit/ug/slau144k/slau144k.pdf
This adds the three general purpose timers on STM32L4 boards in a
central place so that STM32L4 boards can just include it.
Some other families may also have TIM15 and TIM16 and could use this,
but likely some generalization is needed to use this for other
families as well. This can be added later on.
Provide a common clock initialization driver rather than leaving
clock initialization to the boards code. A declarative description of
the board's clock configuration using a struct does still allow to
fine-tune settings. In addition, a board is still allowed to just
provide a custom `void clock_init(void)` if there really is the need
to do crazy things.
19447: boards/nucleo-f429zi: Provide 2nd timer r=benpicco a=maribu
### Contribution description
- Add a common timer config with two (instead of only one) timer using TIM2 + TIM5
- Mostly copy-pasting the cfg_timer_tim2.h and cfg_timer_tim5.h together
- Make use of that for the `nucleo-f429zi`
### Testing procedure
E.g. `tests/periph_timer`, but also grepping for TIM2 and TIM5 in `boards/nucleo-f429zi/include/periph_conf.h` to detect any conflict e.g. between PWM and timer config.

The board uses the USB OTG HS peripheral together with the on-hip FS PHY. Using the `periph_usbdev_hs` module increases the EP data size for the CDC ECM bulk endpoint to 512 bytes, which does not work for the FS interface. Module `periph_usbdev_hs` is therefore not used.
The commit moves the header files from `boards/common/esp32s3/include` that can be used for all types of ESP32x SoCs to a new common ESP32x board module.

19240: tools/doccheck: add simple exclude to doccheck r=benpicco a=kfessel
while doccheck runs for #19228 and #19220, i saw some spikes in memory consumption, turned out that was `grep -Evf dist/tools/doccheck/exclude_patterns` using about 2GB RAM. This PR changes that.
### Contribution description
add `exclude_simple` to `doccheck` drived from `exclude patterns`
`sort`ed and `uniq`ued the simple excludes
removes no longer needed patterns from `exclude patterns`
simple excludes are string rules (no patterns just strings)
how to apply these:
in this PR:
*remove the path and line number from the rule
* that made some of them doubles of each other
* sorted and uniqued them.
* this set of excludes is no longer path specific (an exception covers all paths but may of them still contain a file name)
another possible solution would be to have the excludes line number specific.
### Testing procedure
run `dist/tools/doccheck/check.sh`
compare memory consumption of
master: `grep -Evf dist/tools/doccheck/exclude_patterns`
to
this PR: `grep -Fvf dist/tools/doccheck/exclude_simple`

19249: boards/gd32v: improve board definitions r=benpicco a=gschorcht
### Contribution description
This PR provides some small improvements of the existing board definitions for GD32VF103 boards for more flexibel default configurations and documentation of the board peripherals:
- Allow the remapping of SPI0 pins in SPI configuration (ae984b0bea)
- More flexible I2C configuration (0c337583b4)
The default I2C device configuration allows to define up to two I2C devices `I2C_DEV(0)` and `I2C_DEV(1)`. `I2C_DEV(0)` is always defined if the I2C peripheral is enabled by the module `periph_spi`. The second I2C device `I2C_DEV(1)` is only defined if `I2C_DEV_1_USED` is defined by the board. This allows to use the default configuration with one or two I2C devices depending on whether other peripherals are enabled that would collide with the I2C devices.
- More flexible SPI configuration (edbf59e37e)
The default SPI device configuration allows to define up to two SPI devices `SPI_DEV(0)` and `SPI_DEV(1)`. `SPI_DEV(0)` is always defined if the SPI peripheral is enabled by the module `periph_spi`. The second SPI device `SPI_DEV(1)` is only defined if `SPI_DEV_1_USED` is defined by the board. This allows to use the default configuration with one or two SPI devices depending on whether other peripherals are enabled that would collide with the SPI devices.
Furthermore, the CS signal in the SPI configuration is given by a define that can be overriden with another pin if
the default CS signal is connected to an unused hardware.
- Improve ADC config for Sipeed-Longan-Nano (c9c587ee00)
The ADC configuration was too complex. It was hard to follow when certain ADC lines are available. Furthermore, the order of ADC lines did depend on the use of other peripherals. Now, either the TFT display is not connected and all ADC lines are available or the TFT display is connected and the second SPI device is used so that only the first 4 ADC lines are available.
- Improve Kconfig for Sipeed-Longan-Nano (025f4fdf00)
Board-specific configuration not shown any longer directly in the top level menu but within a submenu.
- Improve peripherals documentation (7f0d560dd8, e24abe495a)
Available peripherals for the board are now documented in two tables ordered by RIOT peripheral names and by pins.
Although the different changes are small and mostly related to the documentation, I could split the PR if necessary.

The default SPI device configuration allows to define up to two SPI devices `SPI_DEV(0)` and `SPI_DEV(1)`. `SPI_DEV(0)` is always defined if the SPI peripheral is enabled by the module `periph_spi`. The second SPI device `SPI_DEV(1)` is only defined if `SPI_DEV_1_USED` is defined by the board. This allows to use the default configuration with one or two SPI devices depending on whether other peripherals are enabled that would collide with the SPI devices.
Furthermore, the CS signal in the SPI configuration is given by a define that can be overriden with another pin if
the default CS signal is connected to an unused hardware.
The default I2C device configuration allows to define up to two I2C devices `I2C_DEV(0)` and `I2C_DEV(1)`. `I2C_DEV(0)` is always defined if the I2C peripheral is enabled by the module `periph_spi`. The second I2C device `I2C_DEV(1)` is only defined if `I2C_DEV_1_USED` is defined by the board. This allows to use the default configuration with one or two I2C devices depending on whether other peripherals are enabled that would collide with the I2C devices.
16782: drivers/mfrc522: add new driver r=benpicco a=HendrikVE
### Contribution description
This PR adds support for the MFRC522. It is quite common in the Arduino world and it is quite cheap. The driver connects to the MFRC522 via SPI and is heavily based on the Arduino driver available [here](https://github.com/miguelbalboa/rfid). Basically it was ported, but with several improvements in readability and documentation.
### Testing procedure
The given (manual) test provides single commands for some driver functions.
19201: cpu/gd32v: add periph_i2c support r=benpicco a=gschorcht
### Contribution description
This PR provides the `periph_i2c` support and is one of a bunch of PRs that complete the peripheral drivers for GD32VF103.
The driver is a modified version of the driver for STM32F1 with some changes that were necessary to get it working on GD32V. As for STM32F1, the driver is using polling instead of interrupts for now. It will be implemented interrupt-driven later.
### Testing procedure
`tests/periph_i2c` as well as a test with any I2C sensor should work. The driver was tested with `tests/driver_l3gxxxx` and `tests/driver_bmp180`.

The default timer configuration has been changed so that `TIMER0` and `TIMER1` are always timer devices. `TIMER2` can only be used as timer device if it is not used for PWM devices. `TIMER3` and `TIMER4` are only available as timer devices if they are supported by the CPU model and not used for PWM devices.
19199: sys/suit: Ensure previous thread is stopped before reusing its stack r=benpicco a=chrysn
### Contribution description
Closes: https://github.com/RIOT-OS/RIOT/issues/19195
If the thread has released the mutex but the thread has not terminated (which happens in the situation that would previously have overwritten a still active thread's state), then a warning is shown and the trigger is ignored.
### Testing procedure
This should work before and after:
* `make -C examples/suit_update BOARD=native all term`
* `aiocoap-client coap://'[fe80::3c63:beff:fe85:ca96%tapbr0]'/suit/trigger -m POST --payload 'coap://[2001:db8::]/foo'`
* In parallel, on the RIOT shell, run `suit fetch coap://[2001:db8::]/foo`
* After the first download fails, the second one starts right away ("suit_worker: update failed, hdr invalid" / "suit_worker: started").
Run again with the worker thread on low priority:
```patch
diff --git a/sys/suit/transport/worker.c b/sys/suit/transport/worker.c
index a54022fb28..e26701a64c 100644
--- a/sys/suit/transport/worker.c
+++ b/sys/suit/transport/worker.c
`@@` -70 +70 `@@`
-#define SUIT_COAP_WORKER_PRIO THREAD_PRIORITY_MAIN - 1
+#define SUIT_COAP_WORKER_PRIO THREAD_PRIORITY_MAIN + 1
```
Before, this runs the download once silently (no clue why it doesn't run it twice, but then again, I claim there's concurrent memory access from two thread, so who knows what happens). After, it runs a single download and shows an error message for the second one once the first is complete ("Ignoring SUIT trigger: worker is still busy.").
### Issues/PRs references
This may be made incrementally easier by https://github.com/RIOT-OS/RIOT/pull/19197 -- that PR as it is now would spare us the zombification (because returning would do that), and having a `wait` function would allow us to turn the new error case into a success.

19050: boards/common/cc26xx cc13xx: clean up and fix flash configs r=benpicco a=maribu
### Contribution description
- Add support for XDS110 debugger via `OPENOCD_DEBUG_ADAPTER=xds110`
- Clean up OpenOCD configs in `boards/common/cc26xx_cc13xx`
- No longer hardcode the debugger to xds110, but use `OPENOCD_DEBUG_ADATER ?= xds110`
- Add support for cc13x0, cc13x2, cc26x0
- `boards/cc2650*`: drop custom OpenOCD config in favor of shared one
- add variables needed to support flashing with `PROGRAMMER=jlink`
- allow specifying a custom OpenOCD command to bring the device to a halt state, as the default `reset halt` (which causes a second reset) is causing issues with the ICEPick JTAG routers in the CC26xx - CC13xx devices
- Use `halt` instead of `reset halt` for CC26xx / CC13xx boards in OpenOCD to avoid issues in flashing
### Testing procedure
```
make BOARD=cc2650-launchpad -C examples/default flash
```
Should now work. The same should still work for other cc26xx cc13xx boards.
