Subject: [PATCH RFT 1/7] dt-bindings: phy: qcom,sc8280xp-qmp-usb43dp: Add mode-switch
Date: Thu, 29 Feb 2024 14:07:01 +0100	[thread overview]
Message-ID: <20240229-topic-sm8x50-upstream-phy-combo-typec-mux-v1-1-07e24a231840@linaro.org> (raw)
In-Reply-To: <20240229-topic-sm8x50-upstream-phy-combo-typec-mux-v1-0-07e24a231840@linaro.org>

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.
