Subject: [PATCH 1/2] ARM: dts: sun6i: Disable display pipeline by default
Date: Thu, 24 Nov 2016 14:43:38 +0800 [thread overview]
Message-ID: <20161124064339.12615-2-wens@csie.org> (raw)
In-Reply-To: <20161124064339.12615-1-wens@csie.org>
While we now support the internal display pipeline found on sun6i, it
is possible that we are unable to enable the display for some boards,
due to a lack of drivers for the panels or bridges found on them. If
the display pipeline is enabled, the driver will try to enable, and
possibly screw up the simple framebuffer U-boot had configured.
Disable the display pipeline by default.
Fixes: 6d0e5b70be13 ("ARM: dts: sun6i: Add device nodes for first
display pipeline")
