: Identifying name for the regulator. | |
struct regulator_desc - Static regulator descriptor Each regulator registered with the core is described with a structure of this type and a struct regulator_config. This structure contains the non-varying parts of the regulator description. : Identifying the regulator supply : Numerical identifier for the regulator. : Regulator operations table. : Interrupt number for the regulator. : Indicates if the regulator is a voltage or current regulator. : Module providing the regulator, used for refcounting. : Number of selectors available for ops.list_voltage(). : Voltage given by the lowest selector (if linear mapping) : Voltage increase with each selector (if linear mapping) : Time to settle down after voltage change (unit: uV/us) : Voltage mapping table (if table based mapping) : Register for selector when using regulator_regmap_X_voltage_ : Mask for register bitfield used for selector : Register for control when using regmap enable/disable ops : Mask for control when using regmap enable/disable ops : Time taken for initial enable of regulator (in uS). | |

regulator_get_voltage_sel_regmap - standard get_voltage_sel for regmap users
: regulator to operate on
Regulators that use regmap for their register I/O can set the vsel_reg and vsel_mask fields in their descriptor and then use this as their get_voltage_vsel operation, saving some code.
