Subject: [PATCH AUTOSEL 4.14 13/26] drm/edid: Add 6 bpc quirk for BOE panel.
Date: Tue, 13 Nov 2018 00:51:37 -0500	[thread overview]
Message-ID: <20181113055150.78773-13-sashal@kernel.org> (raw)
In-Reply-To: <20181113055150.78773-1-sashal@kernel.org>

From: "Lee, Shawn C" <shawn.c.lee@intel.com>

[ Upstream commit 922dceff8dc1fb4dafc9af78139ba65671408103 ]

BOE panel (ID: 0x0771) that reports "DFP 1.x compliant TMDS".
But it's 6bpc panel only instead of 8 bpc.

Add panel ID to edid quirk list and set 6 bpc as default to
work around this issue.
