From 5f9b083cdb55d28a6d3b1bda53121598831a28ad Mon Sep 17 00:00:00 2001 From: Jyotheeswar Reddy Mutthareddyvari Date: Mon, 2 Jan 2017 14:34:51 +0530 Subject: [PATCH] arm64: zynqmp: PM: Specify power domains for DP related nodes Currently DP power domain (pd_dp) is not attached to any of the DP nodes which is causing genpd to trigger a power down request for DP domain, making all DP related peripherals unusable. So assign power domains for all DP related nodes to enable proper accounting of DP power domain usage.
