regulator_get_hardware_vsel_register — get the HW voltage selector register
int regulator_get_hardware_vsel_register ( | struct regulator * regulator, |
unsigned * vsel_reg, | |
unsigned * vsel_mask) ; |
regulator
regulator source
vsel_reg
voltage selector register, output parameter
vsel_mask
mask for voltage selector bitfield, output parameter
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.
