Subject: [PATCH AUTOSEL 5.14 14/75] arm64: dts: rockchip: Disable CDN DP on Pinebook Pro
Date: Tue, 9 Nov 2021 17:18:04 -0500 [thread overview]
Message-ID: <20211109221905.1234094-14-sashal@kernel.org> (raw)
In-Reply-To: <20211109221905.1234094-1-sashal@kernel.org>
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.
