Subject: [not urgent] ROHM PMIC/Charger IC driver maintenance.

Hello All,

In short - I consider adding myself in MAINTAINERs for the ROHM IC
drivers I've authored. I would like to get your opinion as subsystem
maintainers on the area where these driver belong. If you don't care -
then no need to read further :) If you do read, then I would appreciate
hearing about your expectations regarding reviews, ACKs etc.



Longer story, I have contributed drivers for ROHM PMICs
BD71837/BD71847/BD71850, BD70528, BD71828/BD71878 and ROHM charger IC
BD99954. I did also refactor the linear_ranges code out of the
regulator framework. Now I am working on with another PMIC driver
(regulators/watchdog) which I hope to end up in upstream at autumn
after the proper testing. There is also some pieces in regmap-irq which
I have added.

I would like to participate in reviewing work for patches to these
drivers (and perhaps the linear_ranges) and possibly set up some test
jobs where I can run some tests involving some of the PMICs. I hope
this helps the community too.

I would also benefit from being informed when a fix is sent to one of
these areas as I am anyways paid to be hosting some out-of-tree
additions to these drivers. So my git tree would benefit from getting
the odd fixes upstream is getting. Reviewing mails would serve as a
heads up for me.

Thus I consider adding few entries to MAINTAINERs in order to be
getting the patches for review/test. What I don't consider doing is
integrating the patches in "official Linux" - Eg. all patches should
still go upstream via your trees.

What kind of participation would you expect/appreciate from me if I
added myself in MAINTAINERS for these drivers I authored? Any
objections to that? (I don't really know how MAINTAINERs entries should
be added - and I didn't [easily] find up-to-date explanation to that).
For where I can be of help - I believe I am technically competent for
reviewing C-code. I am not competent for reviewing all styling details
- and I am not too useful what comes to YAML - this syntax is still
really alien to me. Yet I think I have some insight to things the DT
yaml is describing (meaning ROHM HW) :)

I add below the list of files / subsystem.
