Any chance you could merge this series (patches 1~7) for 4.5?

The DTS patches can't be merged without the driver updates, and we'd
like to get both parts in.

Updated description:

Patch 1 adds AXP223 to the list of supported chips in the DT binding.

Patch 2 gets rid of the extra "struct device *" parameter from
axp20x_match_device().

Patch 3 makes axp20x_match_device() use dev->driver->of_match_table,
so the function can be library-ized without modification.

Patch 4 splits the axp20x mfd driver into 2 parts, a core library, and
an I2C driver.

Patch 5 cleans up some leftover whitespace issues in axp20x core.

Patch 6 adds an RSB based driver for the AXP223.

Patch 7 adds support for the AXP223 regulators

Patch 8 enables the AXP223 PMIC and its regulators for the Sinlinx
SinA33.

Patch 9 enables the AXP223 PMIC and its regulators for A23/A33 based
Q8 tablet devices.
