Subject: [PATCH 5.15 015/279] arm64: dts: rockchip: Disable CDN DP on Pinebook Pro
From: Matthias Brugger <mbrugger@...e.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.
