Subject: [PATCH v2 0/8] regulator: max77686: Add GPIO control

Hi,

Patch 2/8: not tested on hardware. I am kindly asking for testing it
because I don't have the board with Maxim 77802.

Changes since v1
================
1. Add patch: 1/8 "regulator: max77686: Consistently index opmode
   array by rdev id".
2. Remove patch "regulator: max77686: Make regulator_desc array
   const" (applied).
3. Re-work patches removing from regulators board file support (2/8
   and 3/8). Parse regulators with of_regulator_match() at once, remove
   num_regulators.
4. Patch 4/8: Add depends on OF to mfd/Kconfig. Add Javier's
   reviewed-by.
5. Patch 5/8: Add Javier's reviewed-by.
6. Patch 6/8: Add depends on GPIOLIB to regulator/Kconfig. Rename
   "external control" to "GPIO control" and "ext_control_gpios" to
   simpler "gpios".
   I tried to use new GPIO API but it ended with more problems
   https://lkml.org/lkml/2014/10/29/239

Description
===========
This patch helps in proper description of max77686 regulators in DTS by
allowing to control them over GPIO. This allows removal of
fixed regulators from DTS which duplicate the description of hardware.

The first five patches are cleanups, including board support removal.

The whole patchset should be taken at once.

Patchset is rebased on next-20141023 AND:
1. ARM: EXYNOS: Call regulator suspend prepare/finish
   https://lkml.org/lkml/2014/10/20/545
2. regulator: max77686/trats2: Disable some regulators in suspend
   https://lkml.org/lkml/2014/10/27/280

Best regards,
Krzysztof
