From d3e5b294c6a3e78b9a544eede572e239555224db Mon Sep 17 00:00:00 2001 From: Alexander Kochetkov Date: Tue, 26 Jan 2016 16:34:00 +0300 Subject: [PATCH] clk: rockchip: add hclk_cpubus to the list of rk3188 critical clocks [ Upstream commit e8b63288b37dbb8457b510c9d96f6006da4653f6 ] hclk_cpubus needs to keep running because it is needed for devices like the rom, i2s0 or spdif to be accessible via cpu. Without that all accesses to devices (readl/writel) return wrong data. So add it to the list of critical clocks.
