.BI "int regulator_get_hardware_vsel_register(struct\ regulator\ *\ " "regulator" ", unsigned\ *\ " "vsel_reg" ", unsigned\ *\ " "vsel_mask" ");"
.SH "ARGUMENTS"

regulator source
.RE
.PP
\fIvsel_reg\fR
.RS 4
voltage selector register, output parameter
.RE

\fIvsel_mask\fR
.RS 4
mask for voltage selector bitfield, output parameter

.SH "DESCRIPTION"
.PP
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\*(Aqs back, for example\&.
.PP
On success, the output parameters
\fIvsel_reg\fR
and
\fIvsel_mask\fR
are filled in and 0 is returned, otherwise a negative errno is returned\&.
