Hi, Patches touching max77802 were not tested on hardware. I am kindly asking for testing it because I don't have the board with Maxim 77802. Changes since v2 ================ Re-work the board file support removal after Javier's comments: use new DT style parsing. This imposes a lot of changes. 1. Add "of_compatible" for regulator drivers. 2. Provide backward compatibility if such "of_compatible" is not present. The driver will search for regulators node and use it as dev->of_node. Everything should be bisect-friendly. 3. New patches: 1, 2, 3, 5, 13 and 14. 4. Because of new style DT parsing it is much easier to put "gpio" properties in regulators top node (not in each regulator). This will be also new-gpio-lib friendly. 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.
