This serie aims to enable display support for the stm32mp135f-dk board

Those are only patches of the device-tree since the driver support has
already been added [1].

It respectivelly:
    - adds support for the display controller on stm32mp135
    - adds pinctrl for the display controller
    - enables panel, backlight and display controller on
      stm32mp135f-dk

Finally it fixes the flags on the panel default mode in the
'panel-simple' driver, allowing to override the default mode by one
described in the device tree, and push further the blanking limit on the
panel.

Best regards,

I got the following errors during YAML verification:

Do I miss something ?

I think I messed using a wrong  make option :

make DTBS_CHECK=y W=1 -j$(nproc) st/stm32mp135f-dk.dtb

instead of

make CHECK_DTBS=y W=1 -j$(nproc) st/stm32mp135f-dk.dtb


I'll send a fix promptly.


Thanks,

Raphaël

Alex
