Since v3
- change the node name to be generic 'adc' in binding example.
Since v2
- Change the resistor property name to be generic 'shunt-resistor-micro-ohms'.

+title: RTQ6056 Bi-Directional Current and Power Monitor with 16-bit ADC
+

+
+description: |
+ The RTQ6056 is a high accuracy current-sense monitor with I2C and SMBus
+ interface, and the device provides full information for system by reading
+ out the loading current and power.
+
+ The device monitors both of the drops across sense resistor and the BUS
+ voltage, converts into the current in amperes, and power in watts through
+ internal analog-to-digital converter ADC. The programmable calibration,
+ adjustable conversion time, and averaging function are also built in for
+ more design flexibility.
+
+ Datasheet is available at
+ https://www.richtek.com/assets/product_file/RTQ6056/DSQ6056-00.pdf
