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.
