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.
