NAME¶
regulator_get_hardware_vsel_register - get the HW voltage selector registerSYNOPSIS¶
int
regulator_get_hardware_vsel_register(struct regulator * regulator,
unsigned * vsel_reg,
unsigned * vsel_mask);
ARGUMENTS¶
regulatorregulator 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.AUTHORS¶
