[PATCH v2 0/4] arm64: dts: qcom: qrb5165-rb5: enable DP support

[Dmitry Baryshkov]

Implement DisplayPort support for the Qualcomm RB5 platform.

Note: while testing this, I had link training issues with several
dongles with DP connectors. Other DisplayPort-USB-C dongles (with HDMI
or VGA connectors) work perfectly.

Dependencies: [1]
Soft-dependencies: [2], [3]

displayport-controller does not seem to be a valid child node of the
sm8250 mdss. Please make sure that the binding is updated, if not
already done.

True. I added the compatibility string to dp-controller.yaml, but
missed the mdss schema. I'll send a fix ASAP.

At present RB5 runs against next-master are consistently throwing
warning messages (attached below with call trace) on "Memory manager not
clean during takedown". I can send full logs if required. However, the
runs are booting successfully so the logs are quite big. Tried running
with older dtb built, where these
warnings was not observed.


A bisect (full log below) identified this patch as
introducing the failure.
