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.
