The odroid-xu3 has 4 INA231 current sensors on board which can be accessed from the Linux via the hwmon interface.
There is one sensor for each of these power rails:
- A15 cluster: VDD_ARM
- A7 cluster: VDD_KFC
- GPU: VDD_G3D
- memory: VDD_MEM
In addition to adding the sensors, LDO26 from the PMIC needs to be enabled because it's powering these sensor.

v3: extend existing i2c_0 node v2: use "ti,ina231" as compatible string.
Applies on top of "ARM: dts: Add dts file for odroid XU3 board" from Sjoerd Simons.

OK, let me replace the applied patch with this in my tree.
Thanks, Kukjin
