Akinobu Mita efc945fb72 iio: adc: add support for ADC0831/ADC0832/ADC0834/ADC0838 chips
This adds ADC0831/ADC0832/ADC0834/ADC0838 8-bit ADC driver.
I have tested with ADC0831 and ADC0832.  The remaining ADC0834 and
ADC0838 are very similar to ADC0832.

* Texas Instruments' ADC0831/ADC0832/ADC0832/ADC0838
Required properties:
- compatible: Should be one of
* "ti,adc0831"
* "ti,adc0832"
* "ti,adc0834"
* "ti,adc0838"
- reg: spi chip select number for the device
- vref-supply: The regulator supply for ADC reference voltage
- spi-max-frequency: Max SPI frequency to use (< 400000)
Example:
adc@0 {
compatible = "ti,adc0832";
reg = <0>;
vref-supply = <&vdd_supply>;
spi-max-frequency = <200000>;
};
