Subject: [PATCH] clk: rockchip: also protect hclk_peri as critical
Date: Wed, 10 Sep 2014 17:52:02 +0200 [thread overview]
Message-ID: <1950006.Th78Z9O4lJ@diego> (raw)
The dwc2 usb controller also uses agressive clock gating, which in this
case leads to hclk_peri getting disabled and hanging the system.
Therefore move it to the critical clocks until we also control that
part of the system.
