Sorry for late reply.

static struct clock_event_device ckevt_puv3_osmr0 ...

ckevt_puv3_osmr0.mult =
div_sc(CLOCK_TICK_RATE, NSEC_PER_SEC, ckevt_puv3_osmr0.shift);

Please use the function which calculates the optimizes mult/shift
values for you depending on the clock frequency.

clockevents_calc_mult_shift() is your friend.

Please convert your irq_chips to the new function pointers:

.mask -> .irq_mask
...

The new functions replace the "unsigned int irq" argument with
"struct irq_data *d".

So conversion for your chips is simply

s/unsigned int irq/struct irq_data *d/

and

s/irq/d->irq/ in the implementation.

Then your arch should select: GENERIC_HARDIRQS_NO_DEPRECATED

Otherwise I'm happy with your irq and time related patches.

Thanks,
