From bcd5dfffe6d7827c5c1df96b2e5168036d522220 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 2 Jul 2015 18:16:09 -0600 Subject: dm: video: Add support for the Parade PS8622/625 bridge This chip provides an eDP to LVDS bridge which is useful for SoCs that don't support LVDS displays (or it would waste scarce pins). The setup is included in the device tree.
