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. |
