-* Maxim max9611/max9612 current sense amplifier with 12-bits ADC interface
-
-Maxim max9611/max9612 is an high-side current sense amplifier with integrated
-12-bits ADC communicating over I2c bus.
-The device node for this driver shall be a child of a I2c controller.
-
-Required properties
-  - compatible: Should be "maxim,max9611" or "maxim,max9612"
-  - reg: The 7-bits long I2c address of the device
-  - shunt-resistor-micro-ohms: Value, in micro Ohms, of the current sense shunt
-			        resistor
-
-Example:
-
-&i2c4 {
-	csa: adc@7c {
-		compatible = "maxim,max9611";
-		reg = <0x7c>;
-
-		shunt-resistor-micro-ohms = <5000>;
-	};
-};
-
-This device node describes a current sense amplifier sitting on I2c4 bus
-with address 0x7c (read address is 0xf9, write address is 0xf8).
-A sense resistor of 0,005 Ohm is installed between RS+ and RS- current-sensing
-inputs.
