From 82089116a56ec9a0f608b34405c8bbd0e818b84f Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 1 Sep 2017 09:39:57 +0200 Subject: ARM: dts: Augment VGA connector bridge on PB11MPcore 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.
