    Subject[PATCH 4.4 182/210] clk: rockchip: add hclk_cpubus to the list of rk3188 critical clocks
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Alexander Kochetkov <al.kochet@gmail.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")
