Hi All,

I'd very appreciated if someone can clarify one point for me.

Is allowed/expected/prohibited to use CLK API like clk_enable/disable
in atomic context now on RT-Kernel (HW IRQ or under RAW spinlocks)?

It's not possible, if the spinlock in the clock framework is not a raw
spinlock.
 

How safe is it to allow CLK API to be preemptive?

The functions are protected by the locks. So it's not an issue at all.

Thanks,
