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

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

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

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
