(no changes since v5)

Changes in v5:
- Fix touchscreen resolution to 480x854
- Fix SPI1 CS0 polarity to GPIO_ACTIVE_LOW

Changes in v2:
- Drop the clocks property from the sai1 node in stm32mp257-engicam-microgea-rmm.dts
to avoid overriding the peripheral bus clock reference defined in the base
SoC device tree. Suggested by Sashiko.
- Reference the existing labeled nodes directly at the root level using
&sai1a and &sai1b in stm32mp257-engicam-microgea-rmm.dts instead of
redefining the entire node structure and redeclaring the labels. Suggested by Sashiko.
- Drop the #clock-cells property from sai1a and remove the reference to sai1a from
the clocks array in sai1b, relying strictly on the st,sync property to handle
internal synchronization.

Series is ok, I just have a question regarding board name. Why you don't add the "d" soc information inside the board name as it is done for others STM32 boards ?
