So if there's a drop in processor frequency, the driver times out too early? Not good.

Right now we dont have any way to calculate the timeout.

not even empirically?

So, I have incremented this value to 500 which shall be good enough for the lowest of all frequencies. But I guess what we need here is some formula, to calculate timeout on the basis of frequency, which is nowhere defined.

That's odd - I see a bunch of frequencies advertised in arch/arm/cpu/armv7/exynos/clock.c.

Or how about using a cycle counter instead?

btw, where can I find documentation for the ACE?
