Hartmut Knaack 847e3928de iio:dac:m62332: shutdown on remove
The regulator framework requests to balance regulator_enable() calls with
regulator_disable() calls. To meet this requirement, set channels to 0 on
remove, which implies a regulator_disable() call in case that channel was
enabled.

Hartmut Knaack 862a76acb2 iio:dac:m62332: share scale and offset
This device simply uses its Vcc as reference voltage, so the same scale
applies for all channels. Also offset doesn't appear to be different for
any channel. Represent this by switching these two attributes to
info_mask_shared_by_type.

Dmitry Eremin-Solenikov b87b0c0f81 iio: add m62332 DAC driver
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.
