Subject: [PATCH v4 0/4] regulator support for pmbus and ltc2978
Date: Wed, 1 Oct 2014 14:05:46 -0500 [thread overview]
Message-ID: <1412190349-16343-1-git-send-email-atull@opensource.altera.com> (raw)
From: Alan Tull <atull@opensource.altera.com>
This set of patches adds regulator support for pmbus_core.c and ltc2978.c
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.
Fixes in v4 are not huge:
Add device tree bindings documentation for ltc2978.
rename _pmbus_regulator_enable to _pmbus_regulator_on_off
simplify _pmbus_regulator_on_off code
s/regulator_regulator/regulator/
fix build break when !CONFIG_REGULATOR
remove unused #define PB_OPERATION_CONTROL_SEQ_OFF
fix a #endif comment
simplify probe code, remove added switch statement
remove BUG_ON(), add error message and fix num_regulators
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
* add regulator_desc and of_regulator_match info
* use same structs for all parts; set num_regulators appropriately.
