[U-Boot] [PATCH 10/33] ARM64: zynqmp: DT: Add power domains
Michal Simek
michal.simek at xilinx.com
Thu Apr 7 19:05:39 CEST 2016
From: Soren Brinkmann <soren.brinkmann at xilinx.com>
Add power-domains to the DT and attach devices to them.
The power-domains are all logical domains as understood by firmware.
Each PD is identified by a unique identifier that the platform firmware
understands.
