We've had a nicely calm week, which is what I expected - the last rc
really was bigger just due to random timing issues, and not some
worrying pattern about this release cycle. Whew.
Anyway, there's a couple of regressions still being looked at, but

3.Add auxadc nodes in the mediatek MT2701 dtsi file.

2).Remove 'break' after 'return' i
Add Mediatek auxadc driver based on iio.
It will register a device in iio and support iio.
So thermal can read auxadc channel to sample data by iio device.
It is tested successfully on mt2701 platform.

The commit adds the device tree binding documentation for the mediatek
auxadc found on Mediatek MT2701.
Thermal gets auxadc sample data by iio device.
So the commit changes auxadc device tree binding documentation from
