From: Alan Tull <atull@xxxxxxxxxxxxxxxxxxxxx> Each output has individual on/off control. >From PMBus_Specification_Part_II_Rev_1-3_20140318.pdf: 12.1.1. OPERATION Command Bit [7] Bit [7] controls whether the PMBus device output is on or off. If bit [7] is cleared (equals 0), then the output is off. If bit [7] is set (equals 1), then the output is on. This patchset now uses "regulator: of: Provide simplified DT parsing method" I don't see this patch in Linus's tree or for-next yet, so I applied it to my branch. New in v5: clean whitespace in the DT bindings document add prototypes for the two new functions in pmbus_core.c use "regulator: of: Provide simplified DT parsing method" - remove #include <linux/regulator/of_regulator.h> - remove of_regulator_match in pmbus_driver_info - add of_match and regulators_node for regulator_desc macro - remove pmbus_regulator_parse_dt - remove unneeded 'else' that set init_data and of_node Patch 1: document device tree bindings for ltc2978 Patch 2: add two helper functions for byte pmbus byte operations * byte write and byte read/modify/write Patch 3: regulator support added in pmbus_core.c and pmbus.h * regulator_ops functions (is_enabled, enable, and disable) * gets regulator init data from device tree or platform data * registers the regulators * header has a macro for chip drivers to build their regulator_desc data Patch 4: changes for ltc2978.c * Add Kconfig to enable/disable ltc2978 regulator functionality. * Update list of parts supported in Kconfig. * add regulator_desc info. * use same structs for all parts; set num_regulators appropriately.
