-Analog Devices AD7606 Simultaneous Sampling ADC
-
-Required properties for the AD7606:
-
-- compatible: Must be one of
-	* "adi,ad7605-4"
-	* "adi,ad7606-8"
-	* "adi,ad7606-6"
-	* "adi,ad7606-4"
-	* "adi,ad7616"
-- reg: SPI chip select number for the device
-- spi-max-frequency: Max SPI frequency to use
-	see: Documentation/devicetree/bindings/spi/spi-bus.txt
-- spi-cpha: See Documentation/devicetree/bindings/spi/spi-bus.txt
-- avcc-supply: phandle to the Avcc power supply
-- interrupts: IRQ line for the ADC
-	see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
-- adi,conversion-start-gpios: must be the device tree identifier of the CONVST pin.
-		  This logic input is used to initiate conversions on the analog
-		  input channels. As the line is active high, it should be marked
-		  GPIO_ACTIVE_HIGH.
-
-Optional properties:
-
-- reset-gpios: must be the device tree identifier of the RESET pin. If specified,
-	       it will be asserted during driver probe. As the line is active high,
-	       it should be marked GPIO_ACTIVE_HIGH.
-- standby-gpios: must be the device tree identifier of the STBY pin. This pin is used
-		to place the AD7606 into one of two power-down modes, Standby mode or
-		Shutdown mode. As the line is active low, it should be marked
-		GPIO_ACTIVE_LOW.
-- adi,first-data-gpios: must be the device tree identifier of the FRSTDATA pin.
-		    The FRSTDATA output indicates when the first channel, V1, is
-		    being read back on either the parallel, byte or serial interface.
-		    As the line is active high, it should be marked GPIO_ACTIVE_HIGH.
-- adi,range-gpios: must be the device tree identifier of the RANGE pin. The polarity on
-	      this pin determines the input range of the analog input channels. If
-	      this pin is tied to a logic high, the analog input range is ±10V for
-	      all channels. If this pin is tied to a logic low, the analog input range
-	      is ±5V for all channels. As the line is active high, it should be marked
-	      GPIO_ACTIVE_HIGH.
-- adi,oversampling-ratio-gpios: must be the device tree identifier of the over-sampling
-				mode pins. As the line is active high, it should be marked
-				GPIO_ACTIVE_HIGH.

-
-	adc@0 {

+
+This device is a 12-bit A-D converter with 4 inputs.
+
+The inputs can be used single ended or in certain differential combinations.
+
+For configuration all possible combinations are mapped to 8 channels:

+  1: Voltage over AIN0 and AIN3.
+  2: Voltage over AIN1 and AIN3.
+  3: Voltage over AIN2 and AIN3.
+  4: Voltage over AIN0 and GND.
+  5: Voltage over AIN1 and GND.
+  6: Voltage over AIN2 and GND.
+  7: Voltage over AIN3 and GND.
+
+Each channel can be configured individually:
+ - pga is the programmable gain amplifier (values are full scale)
+    0: +/- 6.144 V
+    1: +/- 4.096 V
+    2: +/- 2.048 V (default)
+    3: +/- 1.024 V
+    4: +/- 0.512 V
+    5: +/- 0.256 V
+ - data_rate in samples per second
+    0: 128
+    1: 250
+    2: 490
+    3: 920
+    4: 1600 (default)
+    5: 2400
+    6: 3300

+   - reg : I2C bus address of the device
+   - #address-cells : must be <1>
+   - #size-cells : must be <0>
+
+  The node contains child nodes for each channel that the platform uses.
+
+  Example ADS1015 node:
+
+    ads1015@49 {
+	    compatible = "ti,ads1015";
+	    reg = <0x49>;
+	    #address-cells = <1>;

+2) channel nodes
+
+  Required properties:
+
+   - reg : the channel number
+
+  Optional properties:
+
+   - ti,gain : the programmable gain amplifier setting
