The periph_dma is not pulled in automatically for all applications.
Applications willing to use the configured peripherals with periph_dma
for a given board will have to include the feature explictly in their
Makefile.

It was causing unrelated issues as threads got de-scheduled while
calling printf and this was not handled properly in tests at that
moment.

RTC and RTT are available and already configured for this board but not provided by the build system

drivers/tps6274x: initial support step-down converter
tests/driver_tps6274x: Added testcase for the step-down converter
boards/jiminy-mega256rfr2: Added TPS6274x config

SPI0_DEV and SPI1_DEV configuration parameters are renamed SPI0_CTRL and SPI1_CTRL to better describe what they define and to avoid confusion with SPI_DEV (0) and SPI_DEV (1).

Used with UART and SPI peripheral

Set BTN0_PIN to GPIO_PIN(2, 5) in board.h

#10611

This configuration provides 1 I2C using I2C1 on PB8 and PB9, which is very common for STMs
