From a0aa6bfebcc729fcbfb1c7ea5751822c4c724765 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Sat, 2 Jun 2018 08:53:40 +0200 Subject: arm64: dts: rockchip: move Chromebook-specific Gru-parts to a separate file Similar to rk3288-Veyron before, the Gru-series does contain Chromebook (aka clamshell laptops) and non-Chromebook devices. And while the two Chromebook devices Kevin and Bob are quite similar, Scarlet the tablet- device is quite different in its design. Therefore move the Chromebook parts into a gru-chromebook dtsi file to make sharing easier.
