    1 * Maxim max9611/max9612 current sense amplifier with 12-bits ADC interface
    2 
    3 Maxim max9611/max9612 is an high-side current sense amplifier with integrated
    4 12-bits ADC communicating over I2c bus.
    5 The device node for this driver shall be a child of a I2c controller.
    6 
    7 Required properties
    8   - compatible: Should be "maxim,max9611" or "maxim,max9612"
    9   - reg: The 7-bits long I2c address of the device
   10   - shunt-resistor-micro-ohms: Value, in micro Ohms, of the current sense shunt
   11                                 resistor
   12 
   13 Example:
   14 
   15 &i2c4 {
   16         csa: adc@7c {
   17                 compatible = "maxim,max9611";
   18                 reg = <0x7c>;
   19 
   20                 shunt-resistor-micro-ohms = <5000>;
   21         };
   22 };
   23 
   24 This device node describes a current sense amplifier sitting on I2c4 bus
   25 with address 0x7c (read address is 0xf9, write address is 0xf8).
   26 A sense resistor of 0,005 Ohm is installed between RS+ and RS- current-sensing
   27 inputs.
