I still have the following yaml error:

arch/arm/boot/dts/st/stm32f769-disco-mb1166-reva09.dtb: panel@0: 'port' 
does not match any of the regexes: 'pinctrl-[0-9]+'
	from schema $id: 
http://devicetree.org/schemas/display/panel/novatek,nt35510.yaml#

It seems that "port" property is missing in "novatek,nt35510.yaml" file, 
can you update it ? Or delete it in the dts file if not needed.

With this change I'll take your series.

I also saw that stm32f769-disco has a similar problem with 
orisetech,otm8009a.yaml file, "backlight" property is not defined.

thanks in advance
Alex
