[PATCH v6 0/3] Add display support on the stm32f746-disco board

From: Dario Binacchi
Date: Wed Jul 12 2023 - 02:29:48 EST


The series adds support for the display on the stm32f746-disco board.

Changes in v6:
- Remove dma nodes from stm32f746-disco.dts, they are not used by LTDC,
so there is no need to enable them.

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.

Changes in v3:
- rename ltdc-pins-a-0 to ltdc-0.
- drop [4/6] dt-bindings: display: simple: add Rocktech RK043FN48H
