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. Changes in v3: - Use struct spi_slave data to access wordlen parameter instead of driver private data. - Move the stm32_spi_is_enabled() helper to the new patch "spi: stm32: add stm32_spi_is_enabled() helper" - Insert blank lines to separate code in ilitek-ili9806e.c Changes in v2: - Rplace tristate with bool in drivers/video/Kconfig Dario Binacchi (9): 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 stm32_spi_is_enabled() helper spi: stm32: add support for bits-per-word setting spi: stm32: extend support to STM32MP25 video: support Rocktech RK050HR345-CT106A panel arch/sandbox/include/asm/test.h | 8 + drivers/spi/sandbox_spi.c | 17 ++ drivers/spi/spi-uclass.c | 22 +- drivers/spi/stm32_spi.c | 71 ++++++- drivers/video/Kconfig | 8 + drivers/video/Makefile | 1 + drivers/video/ilitek-ili9806e.c | 356 ++++++++++++++++++++++++++++++++ include/spi.h | 14 ++ test/dm/spi.c | 16 ++ 9 files changed, 502 insertions(+), 11 deletions(-) create mode 100644 drivers/video/ilitek-ili9806e.c -- 2.43.0 base-commit: 4f70106beafe30df8b0528a3d8b2543cd48fe241
