The sc8280xp Display Port PHYs can be used in either DP or eDP mode and
this is configured using the devicetree compatible string which defaults
to DP mode in the SoC dtsi.
Override the default compatible string for the CRD eDP PHY node so that
the eDP settings are used.
Fixes: 4a883a8d80b5 ("arm64: dts: qcom: sc8280xp-crd: Enable EDP")

Same question here as the one I've sent for Konrad's patch. Is it the
same PHY type, just being repurposed for eDP or is it a different PHY
type?
