Yep, the IIO, regulator, and power subsystem patches all depend on
the MFD patch. Specifically, patches 6, 9, and 10 depend on patch 5.
I can't get rid of this dependency because the variant ID (AXP192_ID)
has to be defined centrally in the MFD patch.

The axp20x_battery patches (last three of the whole series) don't
depend on the variant ID or other defines, so they could be taken
independently through the power subsystem.

Even though the IIO cleanups (7 and 8) don't depend on anything else
I imagine it'd cause problems to take those via IIO because patch 9
depends on them.

IOW: Lee probably needs to take patches 5-10.
