Subject: [PATCH 02/10] ARM: dts: Augment VGA connector bridge on PB1176
Date: Sun, 11 Mar 2018 14:52:59 +0100	[thread overview]
Message-ID: <20180311135307.6271-3-linus.walleij@linaro.org> (raw)
In-Reply-To: <20180311135307.6271-1-linus.walleij@linaro.org>

The PL111 in the ARM reference platforms are connected to
"panels" that are actually dumb VGA DAC connector bridges.
Now that we can support the proper bridges in the DRM driver,
fix this up.
