+ These are members of a family of highly integrated PDA analog
+ interface circuit. They include a 12-bit ADC used for battery,
+ temperature, touchscreen, and other sensors. They also have
+ an audio DAC and amplifier, and in some models an audio ADC.
+ The audio support is highly chip-specific, but most of the
+ sensor support works the same.
Note that the device has to be present in the board's SPI
devices table for this driver to load. This driver doesn't
