[v4,2/4] arm64: dts: qcom: sc8280xp-crd: Introduce pmic_glink
Commit Message
From: Bjorn Andersson <bjorn.andersson@linaro.org>
The SC8280XP CRD control over battery management and its two USB Type-C
port using pmic_glink and two GPIO-based SBU muxes.
Enable the two DisplayPort instances, GPIO SBU mux instance and
pmic_glink with the two connectors on the CRD.

Changes since v3:
- Moved data-lanes into dp/port/endpoint
- Moved dp/port/endpoint definition to sc8280xp.dtsi, and reference by
label - to avoid repeating structure in the dts

This does not work as the drm driver expects 'data-lanes' to be defined
in the controller node where you had it in the previous versions:
[ 6.669325] [drm] Invalid property "data-lanes", default max DP lanes = 4
Moving it to the endpoint nodes would require updating both binding and
driver it seems.

Same here (and for X13s).

I will go back and double-check, but this should be taken care of in
d25cfeeec064 ("drm/msm/dp: parse data-lanes as property of dp_out
endpoint").

That indeed seems to be the case. Sorry about the noise.
I'll just carry the fixes I posted for my sc8280xp 6.2 branches.
