From 35a0efc319023cf845e3eef49176203b862411d6 Mon Sep 17 00:00:00 2001 From: Alistair Francis Date: Fri, 17 Feb 2017 10:49:58 -0800 Subject: [PATCH] arm64: zynqmp: Update dom0 bootargs to allow device passthrough Dom0 has access to all of the clocks and turns off clocks that it isn't using. This breaks device passthrough for other guests. This patch tells Dom0 to not disable the clocks allowing device passthrough.
