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.
