[v6,00/13] Add support for AXP192 PMIC

  This series adds support for the AXP192 PMIC to the AXP20x MFD driver
framework, including support for regulators, ADCs, and AC/USB/battery
power supplies.

v6 is a resend of v5 from July -- the patches haven't changed at all
but I've rebased them on the latest git master branch.

Whoops, forgot the link to v5. Here it is:

Hi Aidan,

Lee has recently expressed that he keen to take as much of these sorts
of series as possible via the various subsystem trees.

As such, it is useful to call out in the cover letter of such a series
if this can be done.  For example, patch 9 (last IIO one) can't be
applied without defines in patch 6 (I think).  Thus I'm assuming Lee
will do an immutable branch with at least those patches on it.

Perhaps worth expressing if that is also the case for the power
and regulator subsystem patches?

Thanks,

Jonathan

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.

There are two types of dependencies: compile and functional.

It's not clear which one you are talking about. If it's functional,
then each driver can be taken separately via each concerned subsystem.

Johnathan was talking about compile dependencies -- the defines he's
mentioning -- so what I mean is compile dependencies. Patches 6/9/10
do not compile unless they are applied after patch 5, because of a new
enumerator AXP192_ID defined in patch 5.
