From e1dc2b2e1bef7237fd8fc055fe1ec2a6ff001f91 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 12 Dec 2018 15:51:50 -0800 Subject: ARM: bcm283x: Switch V3D over to using the PM driver instead of firmware. The GRAFX domain only contains V3D, and this driver should be the only accessor of V3D (firmware usage gets disabled when V3D is in the DT), so we can safely make Linux control the GRAFX and GRAFX_V3D power domains.
