The assumption that every MCU has this feature turned out wrong. Hence,
add a feature to allow testing for support of edge triggered IRQs on
both flanks.
This adds the features
- periph_gpio_ll_input_pull_down:
To indicate support for input mode with internal pull down
- periph_gpio_ll_input_pull_keep:
To indicate support for input mode with internal resistor
pulling towards current level
- periph_gpio_ll_input_pull_up:
To indicate support for input mode with internal pull up
- periph_gpio_ll_disconnect:
To indicate a GPIO can be disconnected
- periph_gpio_ll_open_drain:
To indicate support for open drain mode
- periph_gpio_ll_open_drain_pull_up:
To indicate support for open drain mode with internal pull up
- periph_gpio_ll_open_source:
To indicate support for open source mode
- periph_gpio_ll_open_source_pull_down:
To indicate support for open source mode with internal pull down
This introduces KCONFIG_BOARD_CONFIG and KCONFIG_CPU_CONFIG variable for
boards and CPUs (including common directories) to add default
configuration files to be merged. The current approach, as it uses
Makefile.features, would include boards first, not allowing them to
override CPU configurations.
The RTT overflow callback is not available on all RTT implementations.
This means it is either a no-op or `rtt_set_overflow_cb()` is a no-op
or it will overwrite the alarm set with `rtt_set_alarm()`.
This adds a feature to indicate that proper overflow reporting is available.
Some periph_rtt implementations do not provide `rtt_set_counter()`. This
adds `periph_rtt_set_counter` as feature to allow testing for its
availability. The feature is provided at CPU level if periph_rtt is
provided by the board for all CPUs implementing `rtt_set_counter()`.
In STM32MP1 family, independant watchdogs (IWDG1 and IWDG2) are
dedicated to the MPU (Cortex-A7). Thus simply disable the feature
for STM32MP1 family.

The stm32mp1 family has no flash. The firmware is loaded directly in
RAM by stlink programmer or by Cortex-A7 bootloader/OS.
Thus bootloader is useless for this family, disable it.

Seems like the Interrupt flag for a Capture/Compare channel gets set when
- the CC-value is reached
- the timer resets before the CC value is reached.
We only want the first event and ignore the second one. Unfortunately I did
not find a way to disable the second event type, so it is filtered in software.
That is we need to
- ignore the CC-interrupts when the COUNT register register is reset
- ignore the CC-interrupts > TOP value/ARR (auto-reload register)
The STM32 line of microcontrollers comes with a bootloader in the ROM.
It provides the option to flash the device firmware in DFU mode (USB)
or via UART or SPI.
To enter the bootloader we have to jump to a specific address in memory,
but before reset the CPU to make sure the system is in a known state.
This enables us to use the usb_board_reset module on all STM32 platforms.
All members of the stm32f401* family (etc) don't have the HWRNG
peripheral.
Apply a broader wildcard so we don't have to touch this file when
adding new boards with slightly different MCUs.
The old limitation is not valid anymore, we can evaluate $(CPU_MODEL)
here directly.
The output of
make -C tests/periph_hwrng info-boards-supported | wc -w
remains the same.
