[PATCH 1/2] mfd: max5970: Rename driver and remove wildcard

[Naresh Solanki]

The previous version of this driver included wildcards in file names
and descriptions. This patch renames the driver to only support MAX5970
and MAX5978, which are the only chips that the driver actually supports.

This does not apply cleanly.  Rather than mess you around, I'll apply
the MFD driver and provide a PR for Mark.  Perhaps this will apply to
the regulator tree.

Testing now - please stand-by.

Re: [PATCH 1/2] mfd: max5970: Rename driver and remove wildcard

[Naresh Solanki]

Hi Lee,

I hope this email finds you well. I am writing to inquire about the 
status of my patch.

The purpose of this patch set was to rename the driver to remove the 
wildcard and make it specific to avoid confusion with different similar 
devices. I want to emphasize that this patch set does not include any 
functional changes.

I would appreciate it if you could kindly provide an update on the 
status. Please let me know if there is anything else you need from my 
end to help move things forward.

Thank you for your time and attention.

Best regards,
Naresh Solanki

Please refrain from top-posting.

If you think your patch has fallen through the gaps (it hasn't) please
submit a [RESEND].

The merge-window has been open for the last 2 weeks.  I'm just ramping
up again on my backlog.

I'll get to you soon.

So multiple devices are supported:

  MAX5970  ... AND
  MAX5978  ... thus
  MAX597X  ... does make sense, no?
 
 What are you trying to achieve?

Understood. It is important to note that there are indeed other 
unrelated chips in addition to MAX5970 and MAX5978. Examples include 
MAX5971, which is a Single-Port, 40W, IEEE 802.3af/at PSE Controller 
with Integrated MOSFET, and MAX5974A, an Active-Clamped, 
Spread-Spectrum, Current-Mode PWM Controller, among others.

With this change, the intention is to be specific about the chips the 
driver supports. Instead of using wildcards or a broad "MAX597X" 
designation, the patch aims to exclusively support the MAX5970 and 
MAX5978 chips.

It's a tricky situation when engineers/marketing people name devices in
a nonsensical manner.  However, "max5970" just as misleading in this
context as "max597x", thus the patch doesn't improve anything.  It's
more of a maneuver side-ways.

After considering the feedback received regarding the context of the 
leaf driver for max5970, it has been recommended to specifically use 
"max5970" instead of a general designation like "max597x." However, for 
support related to max5978, the documentation can be referred to.

Therefore, this change is necessary in order to unblock the leaf driver 
and address the feedback received.

[PATCH v11 0/3] regulator: Add X-Powers AXP15060/AXP313a PMIC support

[Andre Przywara]

Hi,

this patch series adds support for the X-Powers AXP15060 and AXP313a
PMIC, which are general purpose PMICs as seen on different boards with
different SOCs, mostly from Allwinner.

This is mostly a repost of the previous patches, combining both the
AXP313a and AXP15060 series, rebased on top of v6.4-rc3, and omitting
the patches that already got merged.
The first two patches are the successors of the AXP313a v10 post,
the third patch is based on Shengyu's AXP15060 v3 post.

There were no code changes, just some tiny context differences due to
the rebase, plus I added the newly gained tags.

As the DT bindings and the AXP15060 MFD part are already in the tree,
this is just completing support with the MFD part for the AXP313a, and
the regulator support for both PMICs.

Shengyu, Martin: can you please give this a final test?

Cheers,
Andre
