[PATCH 0/2] arm64: dts: qcom: add DP Controller to SM8550 DTS

[PATCH 0/2] arm64: dts: qcom: add DP Controller to SM8550 DTS

[Neil Armstrong]

The DP output is shared with the USB3 SuperSpeed lanes and is
usually connected to an USB-C port which Altmode is controlled
by the PMIC Glink infrastructure.

DT changes tying the DP controller to the USB-C port on the QRD
board will be sent later.

[PATCH 1/2] dt-bindings: display: msm: dp-controller: document SM8550 compatible

[Neil Armstrong]

The SM8550 & SM8350 SoC shares the same DP TX IP version, use the
SM8350 compatible as fallback for SM8550.
