Hi Bence,

I'm mostly statisfied with this patch now, but I have one minor
suggestion below.

We don't use the irq member during the driver operation, so I don't
think this value needs to be saved here with the driver data. It seems
to only be needed in mchp_tc_irq_enable() for devm_request_irq().
Perhaps you can pass the irq value as a parameter to
mchp_tc_irq_enable() instead.

With that change made, I think I'll be ready to pick up this patchset
and merge it into counter-next.
