From 00eb60a8b4f7a4aa00fd8abd68c2dc7aec55df19 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Mon, 23 Feb 2015 18:40:12 +0100 Subject: ARM: imx6: gpc: Add PU power domain for GPU/VPU When generic pm domain support is enabled, the PGC can be used to completely gate power to the PU power domain containing GPU3D, GPU2D, and VPU cores. This code triggers the PGC powerdown sequence to disable the GPU/VPU isolation cells and gate power and then disables the PU regulator. To reenable, the reverse powerup sequence is triggered after the PU regulator is enabled again. The GPU and VPU devices in the PU power domain temporarily need to be clocked during powerup, so that the reset machinery can work.
