v16:
- Improve vdd regulator comments
v15:
- Address comments on the patches
v14:
- Merge the thermal driver and hwmon
v13:
- Address comments on thermal driver
- Rebase on master (without other patches)
v12:
- Rebase
v11:
- Address comments on hwmon
- Improve "mfd: simple-mfd-i2c: Add a Kconfig name" commit message
v10:
- Use dev_get_regmap() instead of dev_get_drvdata()
v9:
- Convert to use the simple-mfd-i2c instead

There are still some checkpatch warnings.

Please fix those as well as the trivial CHECK messages reported by
checkpatch --strict. A MAINTAINERS update isn't needed, though,
unless you want to.

There are still some checkpatch warnings.

Please fix those as well as the trivial CHECK messages reported by
checkpatch --strict. A MAINTAINERS update isn't needed, though,
unless you want to.
