10   Returns the hardware register offset and bitmask used for setting the
11   regulator voltage. This might be useful when configuring voltage-scaling
12   hardware or firmware that can make I2C requests behind the kernel's back,
13   for example.
14   </p><p>

16   On success, the output parameters <em class="parameter"><code>vsel_reg</code></em> and <em class="parameter"><code>vsel_mask</code></em> are filled in
17   and 0 is returned, otherwise a negative errno is returned.
