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.

v2: use "ti,ina231" as compatible string.

Applies on top of "ARM: dts: Add dts file for odroid XU3 board" from Sjoerd Simons.

It's ok but IMHO it can split using label reference, e.g. 

&i2c_0 {
	...
};

Yes, you're right.  I'll spin a v3.
