RE: [PATCH V2 3/4] arm/imx6q: register arm_clk as cpu to clkdev

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Is there a portable/generic approach for other drivers that may
want to use arm-cpufreq.c? arm_clk is not normally defined for
my SoC and I don't see an easy way to pull it in.

cpufreq needs cpu clock to change frequency.
