[Nouveau] [PATCH 0/2] Support for INA3221 power sensor

[Karol Herbst]

The INA3221 is usually found on mid and high end kepler+ gpus

Marins Patch implements the new iccsense subdev and all needed bits for the
INA3221 power sensor.

My Patch implements the hwmon power1 interface to expose the current power
consumption through hwmon (and can be read out via sysfs or the sensors tool)

Please test these patches for Fermi+ GPUs, that nothing gets messed up and
works as expected. There shouldn't be an entry for hwmon when there is no
usable power sensor. And if you have a INA3221 (EXTDEV table in the vbios) then
it should export the power consumption. If not, please report to either of us.

Thanks
