[RFC][PATCH 3/5] hi655x-pmic: Fixup issue with un-acked interrupts

From: John Stultz
Date: Wed Jun 01 2016 - 17:28:41 EST

While trying to get the powerkey to function, I found
when pressing the key, I would get infinitely repeating

After digging around a bit, it seems we didn't set the
ack_base value for the regmap irqchip logic, so nothing
was acking the interrupt.

This patch adds the ack_base, which seems to make things
