Subject: [PATCH v2 2/5] mfd: rn5t618: add irq support

---

This adds support for irq handling in the rc5t619 which is required
for properly implementing subdevices like rtc.
For now only definitions for the variant rc5t619 are included.

Signed-off-by: Andreas Kemnade <[email protected]>

Changes in v2:
- no dead code, did some more testing and thinking for that
- remove extra empty lines

after having some more look at it, I think I should note the interrupts
property in the bindings documentation since it gets used by using
i2c->irq. Will probably send a v3 the next days.

For what it's worth, the boards I have (Archos 101 Oxygen and Pipo P9)
with rc5t619 use GPIO for power button.
So IRQ would need to be enabled in suspend for this to work.
Also, since you actually added alarm support, perhaps you want to
wake-up from suspend using alarm as well?

Already tested that, that works, because device_init_wakeup() is used.
disable_irq() is needed because we cannot do i2c that early after resume.
Other mfd drivers do thas as well and waking up works.
