From 7ec3e67307f8611b5db7f76048505df9393563ea Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Fri, 28 Aug 2020 13:40:50 -0700 Subject: [PATCH] arm64: dts: qcom: sc7180-trogdor: add initial trogdor and lazor dt This is essentialy a squash of a bunch of history of trogdor and lazor dt updates from the chromium kernel tree. I don't claim any credit other than wanting to more easily boot upstream kernel on these devices. I've tried to add cc tags for all the original authors.
