From: Matthias Brugger <mbrugger@suse.com>
[ Upstream commit 2513fa5c25d42f55ca5f0f0ab247af7c9fbfa3b1 ]
The CDN DP needs a PHY and a extcon to work correctly. But no extcon is
provided by the device-tree, which leads to an error:
cdn-dp fec00000.dp: [drm:cdn_dp_probe [rockchipdrm]] *ERROR* missing extcon or phy
cdn-dp: probe of fec00000.dp failed with error -22
Disable the CDN DP to make graphic work on the Pinebook Pro.

[ Upstream commit 75dccea503b8e176ad044175e891d7bb291b6ba0 ]
Per Documentation/devicetree/bindings/arm/coresight-cpu-debug.txt.
This IP block can be used for sampling the PC of any given CPU, which is
useful in certain panic scenarios where you can't get the CPU to stop
cleanly (e.g., hard lockup).
