  The MSM8226 TSENS IP has 6 thermal sensors in a TSENS v0.1 block.
The thermal sensors use non-standard slope values.

Matches the configuration found in msm8226-v2.dtsi in msm-3.10 kernel.

Note, the driver from 3.10 also provides custom data for non-calibrated 
mode. We can either ignore that (in the hope that all devices leaving 
the factory are calibrated), or fix it in the manner close to 8x74.

That is true, 3.10 kernel does support non-calibrated mode. I can add support for that in a new version if that is wanted.

If there are no other comments, I'd suggest sending that as a follow
up (if sending it at all). The tsens driver provides some default
values for non-calibrated mode, so it is a minor issue.
