Subject: [PATCH] arm64: dts: rockchip: Disable CDN DP on Pinebook Pro
Date: Thu, 15 Jul 2021 18:41:01 +0200	[thread overview]
Message-ID: <20210715164101.11486-1-matthias.bgg@kernel.org> (raw)

From: Matthias Brugger <mbrugger@suse.com>

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.

Reported-by: Guillaume Gardet <guillaume.gardet@arm.com>
