[PATCH] ARM: tegra: harmony: Add ADT7641 temperature sensor

[Thierry Reding]

The Harmony board has an Analog Devices ADT7461 temperature sensor
connected to the DVC bus. It can be used to monitor the ambient (local)
and on-die (remote) temperatures.

Note that I haven't actually tested this, as I no longer have access to
Harmony hardware. Testing can easily be done either by reading the files
from sysfs directly or by running the sensors utility from the
lm-sensors package.

OK, I can test this. The same comment about the DT node name that I
made for the other patch applies here too.

Alright, I'll rename the node.

Ventana also has the same sensor and due to git am applying your patch
to the wrong file (I've renamed all my .dts files), I ended up testing
that too, so you may as well send a second patch for Ventana. Ventana
has an nct1008 though.

Okay, will do. Thanks for testing.
