Thanks for doing the conversion.

dt_binding_check was not happy:
Documentation/devicetree/bindings/display/panel/rocktech,rk070er9427.example.dt.yaml: panel: 'backlight', 'port' do not match any of the regexes: 'pinctrl-[0-9]+'
  DTC     Documentation/devicetree/bindings/display/panel/friendlyarm,hd702e.example.dt.yaml

Error: Documentation/devicetree/bindings/display/panel/sitronix,st7701.example.dts:22.42-43 syntax error
FATAL ERROR: Unable to parse input tree

Please fix and check the bindings using dt_binding_check before
resubmit.

I had to install libyaml-dev (as least I recall this was the name)
before dt_binding_check worked OK for me.
