[PATCHv2 0/4] Regmap IRQ fix and related changes CPCAP

[Tony Lindgren]

Hi all,

Here's v2 set of fixes to make CPCAP PMIC interrupts work reliably when
used with multiple drivers. While working on the ADC, charger and
USB PHY drivers I noticed that the PMIC interrupt to the SoC would
eventually stop working.

All these can wait for v4.12 merge window as these issues don't show
up currently. Two of the patches are also harmless currently, so I've
kept them in this series to avoid pointless merge conflicts.

Regards,

Tony

Changes since v1:

- Updated regap-irq patch to use out_runtime_put in regmap_irq_thread
  also if pm_runtime_get() fails

- Clarify patch description for regmap-irq changes to make clear
  this is an issue with the CPCAP PMIC and not SoC GPIO edge/level
  handling based on comments from Charles Keepax
  <ckeepax@xxxxxxxxxxxxxxxxxxxxxxxxxxx>

- Collected acks
