    cpufreq: imx6q: Fix clock enable balance · fae19b84
    Sascha Hauer 提交于
    For changing the cpu frequency the i.MX6q has to be switched to some
    intermediate clock during the PLL reprogramming. The driver tries
    to be clever to keep the enable count correct but gets it wrong. If
    the cpufreq is increased it calls clk_disable_unprepare twice
    on pll2_pfd2_396m. This puts all other devices which get their clock
    from pll2_pfd2_396m into a nonworking state.
    
    Fix this by removing the clk enabling/disabling altogether since the
    clk core will do this automatically during a reparent.
