[PATCH 4/4] dt-bindings: display: sitronix, st7701: document port and rotation

[Krzysztof Kozlowski]

Panels are supposed to have one port (defined in panel-common.yaml
binding) and can have also rotation:

  rk3326-odroid-go3.dtb: panel at 0: 'port', 'rotation' do not match any of the regexes: 'pinctrl-[0-9]+'
