[PATCH v4 0/2] Add MPS MP5920 Host-Swap controller

[PATCH v4 0/2] Add MPS MP5920 Host-Swap controller

[Alex Vdovydchenko]

This series of patches adds the MP5920 Host-swap controller, which is used
as a protection and control IC for devices that are being inserted into a live
backplane. MP5920 acts as a voltage regulator (MP5911 etc) supervisor. IC
utilizes pmbus and provides monitoring, statistics and limits to electrical and
thermal characteristics such as:
- input and output voltage
- output current
- output power
- IC temperature

One must take into account the nonlinear character of readings, so there will be
a statistical error in the range 5–10 percents, depending on current passing
through. In order to use the IC, make sure to specify a valid I2C address
(consult to datasheet and dts-bindings)
MP5920 datasheet: https://www.monolithicpower.com/en/mp5920.html

Changes in v2:
  -  fixed typos
Changes in v3:
  -  removed unnecessary license blob
  -  removed unnecessary headers
  -  edited device tables style
  -  added chip name checking in probing
  -  fixed typos in pmbus_driver_info struct initialization
Changes in v4:
  -  added i2c_check_functionality in probing
  -  refactored usage of dev_err_probe insted of dev_err
  -  edited chip name string handling while printing
  -  restored .driver.of_match_table, keeping i2c_driver "old" style

So you keep ignoring and ignoring?

<form letter>
This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.

https://elixir.bootlin.com/linux/v6.5-rc3/source/Documentation/process/submitting-patches.rst#L577

If a tag was not added on purpose, please state why and what changed.
</form letter>

Best regards,
Krzysztof

That isn't mandatory; checkpatch asks for it, but I prefer not to have it
in the first place if the submitter doesn't really plan to maintain it.
