2015-05-17iio: add m62332 DAC driverDmitry Eremin-Solenikov3-0/+280
m62332 is a simple 2-channel DAC used on several Sharp Zaurus boards to control LCD voltage, backlight and sound. The driver use regulators to control the reference voltage and enabling/disabling the DAC.

None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.
