REGULATOR_GET_HARDWA(9)                   API reference                   REGULATOR_GET_HARDWA(9)



NAME
       regulator_get_hardware_vsel_register - get the HW voltage selector register

SYNOPSIS
       int regulator_get_hardware_vsel_register(struct regulator * regulator,
                                                unsigned * vsel_reg, unsigned * vsel_mask);

ARGUMENTS
       regulator
           regulator source

       vsel_reg
           voltage selector register, output parameter

       vsel_mask
           mask for voltage selector bitfield, output parameter

DESCRIPTION
       Returns the hardware register offset and bitmask used for setting the regulator voltage.
       This might be useful when configuring voltage-scaling hardware or firmware that can make
       I2C requests behind the kernel's back, for example.

       On success, the output parameters vsel_reg and vsel_mask are filled in and 0 is returned,
       otherwise a negative errno is returned.
