From a3e6e13addee8335926e4e5ea4e8f5caf98e783c Mon Sep 17 00:00:00 2001 From: John Stultz Date: Fri, 23 Sep 2016 17:01:05 -0700 Subject: [PATCH] arm: dts: qcom: apq8064-nexus7: Add DSI and panel nodes Add DSI and panel nodes to get graphics up and running on the Nexus7. This still depends on the panel driver being present along with the rpmclk code. Feedback would be greatly appreciated!
