[PATCH 0/3] DisplayPort support for SM6350/SM7225

[PATCH 0/3] DisplayPort support for SM6350/SM7225

[Luca Weiss]

Add the required changes to support DisplayPort (normally(?) available
via the USB-C connector) on the SM6350/SM7225 SoC.

This has been tested on a Fairphone 4 smartphone with additional changes
not included in this series (mostly just wiring up TCPM and the SBU
mux).

Re: [PATCH 1/3] dt-bindings: display: msm: dp-controller: document SM8250 compatible

[Luca Weiss]

Stupid typo in subject, should of course be SM6350, not SM8250.

Just use 'contains' here with qcom,sm6350-dp. The full schema will check 
the order.
