From: Kevin Hilman <[email protected]> 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.
