From dfdc2488c324af6a794316b4831de6e3f20c65c9 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 23 Jan 2018 14:02:00 +0100 Subject: [PATCH] ARM: dts: Augment VGA connector bridge on Realview EB 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.
