From d2a3671ebe6479483a12f94fcca63c058d95ad64 Mon Sep 17 00:00:00 2001 From: Leo Yan Date: Fri, 1 Sep 2017 08:47:14 +0800 Subject: [PATCH] clk: hi6220: mark clock cs_atb_syspll as critical Clock cs_atb_syspll is pll used for coresight trace bus; when clock cs_atb_syspll is disabled and operates its child clock node cs_atb results in system hang. So mark clock cs_atb_syspll as critical to keep it enabled.
