This series adds support for the Rocktech RK050HR345-CT106A panel.
The initialization of this panel requires a 9-bit word length
configuration. To support this, I have extended the STM32 SPI driver
(including support for the STM32MP25 SoC) to implement the set_wordlen
operation.

To properly validate these changes and ensure the SPI uclass correctly
handles the word length propagation, I have also implemented the
corresponding logic in the sandbox driver and added a dedicated unit
test.

I have grouped these patches together to provide a complete overview of
the implementation and its verification.


Dario Binacchi (8):
  spi: add support for bits-per-word setting
  spi: sandbox_spi: support wordlen setup
  test: spi: add sandbox_spi_get_wordlen interface
  test: dm: spi: add testcase for spi_set_wordlen()
  spi: stm32: clean up buffer length assignment
  spi: stm32: add support for bits-per-word setting
  spi: stm32: extend support to STM32MP25
