Subject: [PATCH 4.2.y-ckt 021/218] clk: rockchip: add hclk_cpubus to the list of rk3188 critical clocks
4.2.8-ckt7 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Alexander Kochetkov <al.kochet@...il.com>
commit e8b63288b37dbb8457b510c9d96f6006da4653f6 upstream.
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.
Fixes: 78eaf6095cc763c ("clk: rockchip: disable unused clocks")
