From 356150e86d75653d1f679c6ef583144b26d0a686 Mon Sep 17 00:00:00 2001 From: Douglas Anderson Date: Thu, 11 Apr 2019 16:21:57 -0700 Subject: [PATCH] ARM: dts: rockchip: vdd_gpu off in suspend for rk3288-veyron At some point long long ago the downstream GPU driver would crash if we turned the GPU off during suspend. For some context you can see: https://chromium-review.googlesource.com/#/c/215780/5..6/arch/arm/boot/dts/rk3288-pinky-rev2.dts At some point in time not too long after that got fixed. It's unclear why the GPU is left enabled during suspend on the mainline kernel. Everything seems fine if I turn this off, so let's do it.
