Subject: [PATCH] MAX8997/8966 MFD: Add IRQ control feature
This patch enables IRQ handling for MAX8997/8966 chips.
Please note that Fuel-Gauge-related IRQs are not implemented in this
initial release. The fuel gauge module in MAX8997 is identical to
MAX17042, which is already in Linux kernel. In order to use the
already-existing MAX17042 driver for fuel gauge module in MAX8997, the
main interrupt handler of MAX8997 should relay related interrupts to
MAX17042 driver. However, in order to do this, we need to modify
MAX17042 driver as well because MAX17042 driver does not have any
interrupt handlers for now. We are not going to implement this in this
initial release as it is not crucial in basic operations of MAX8997.

The changes from previous patch
v8
removed unnecessary code and fixed errors.
v7
removed RTC patch from the series as applied
with comments from Stephen
- Removed dependencies on not setting
"CONFIG_GENERIC_HARDIRQS_NO_DEPRECATED"
v6
with comments from Samuel
- IRQ register bit values use macros
corrected GPIO interrupt handling
RTC configuration bit values use macros
v5
with comments from Mark
- Style updated for PMIC
- Revised side-effect calculation
In the range given, choose a setting without side-effect
then, choose a setting with the least side-effect if allowed.
Added comments on FUEL-GAUGE issue in IRQ
v4
with comments from Randy:
- Spelling errors in Kconfig
with comments from Minsung Kim:
- RTC month bit error.
v3
with comments from Joe:
- Style updated for IRQ and RTC
with comments from Mark
- Style updated for RTC and PMIC
Merged support for RTC and IRQ
v2
with comments from Samuel:
- Style updated for MFD
with comments from Mark:
- Updated API for next and 2.6.38
- Style updated for regulators
Support for hibernation
Support for bulk register access
Corrected register names
Added RTC/IRQ registers
LDO access bug fixed
Support for regulator suspend state control
