From 3088a5c7ad990b8ac2afb6dbfeae25c67392c6e9 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Tue, 23 Jan 2018 13:32:09 +0100 Subject: ARM: dts: Augment VGA connector bridge on PB1176 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.
