Signed-off-by: Dario Binacchi Reviewed-by: Raphaël Gallais-Pou --- Changes in v5: I am confident that framebuffer sizing is a real requirement for STM32 boards, but I need some time to understand if and how to introduce this functionality. Therefore, I drop the following patches to allow the series to be fully merged: - [4/6] dt-bindings: display: stm32-ltdc: add optional st,fb-bpp property - [5/6] ARM: dts: stm32: set framebuffer bit depth on stm32f746-disco - [6/6] drm/stm: set framebuffer bit depth through DTS property Changes in v4: - Use DTS property instead of module parameter to set the framebuffer bit depth.
