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.
