Subject: [PATCH RFT 1/7] dt-bindings: phy: qcom,sc8280xp-qmp-usb43dp: Add
 mode-switch

The QMP USB3/DP Combo PHY can work in 3 modes:
- DisplayPort Only
- USB3 Only
- USB3 + DisplayPort Combo mode

In order to switch between those modes, the PHY needs to receive
Type-C events, allow marking to the phy with the mode-switch
property in order to allow the PHY to Type-C events.

Signed-off-by: Neil Armstrong <neil.armstrong@...aro.org>
