From 5acd351427361131c583dfb11c7bf4c364c98a9b Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Fri, 10 Nov 2017 15:27:25 +0100 Subject: drm/tegra: Move common plane code to separate file Subsequent patches will add support for Tegra186 which has a different architecture and needs different plane code but which can share a lot of code with earlier Tegra support.
