changes in v5:
- fixed commit message on v5-0002 and v5-0004
changes in v4:
- fixed attributes groups review comments in v3
- added new bug fix patches v4-0007 and v4-0008
changes in v3:
- fixed dt_binding_check error
- fixed spelling usb->USB
changes in v2:
- fixed spelling
- revert back probe to probe_new in mfd driver
I do not see a cover letter, but FWIW,
Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com>
for all patches except DT binding
Note, some of the comments regarding spelling were given, I believe
you are going to address them in v3.

Input voltage channel enum is compared against iio address instead
of the channel.

The mfd cell devices name populated on sysfs entry is dynamically derived
from an auto instance which introduced a regression. As a result
mpc2629_charger driver failed to get adc channel because of iio consumer
name mismatch with the sysfs.

Allows the user to change the USB device fast charge setting to advertise
host on enumeration helps to accelerate the charging cycle. Altering this
value resets USB existing connection.

Hmm. this is going to slow things down wrt to this series going in.
We want the associated fix to go in during this cycle, and this
is dependant on a change going via MFD. Ah well.
Generally I prefer to avoid using chip IDs for this sort of check
because they don't generalize as well as an actual flag for this
'feature' stored in a chip_info type structure.
However, we can tidy that up if it becomes relevant as more parts
are added to the driver.
On basis this might end up going via MFD,

There is a small ordering issue wrt to the next patch.
Ideal way to solve that is to introduce the new infrastructure
for the chip ID, but not the new ID itself until after the next
patch ensures we don't apply the wrong mask.

I suppose you do not actually want to get this merged concidering
you did not carry over the Acked-by you got in v4? :)
