[RFC PATCH 0/2] PM6125 regulator support

[Iskren Chernev]

This patch series adds SPMI and SMD regulator support for the PM6125 found on
SM4250/SM6115 SoCs from QCom.

The main source used for this change is qpnp pm6125 support patch from caf [1]:

[1]: https://source.codeaurora.org/quic/la/kernel/msm-5.4/commit/?h=kernel.lnx.5.4.r1-rel&id=d1220daeffaa440ffff0a8c47322eb0033bf54f5

Unfortunatelly the source patch doesn't contain regulator source groups, so all
regulators define their own source. If that was available (suggestions are
welcome), this patch could become acceptable.

While at it I have a few suggestions:
- spmi determines how to treat each regulator based on type,subtype,revision
  read from regulator register. I assume this information is fixed for a givem
  PM chip. It would be really helpful if it was available somewhere in code
  (comment) or maybe the commit message, so correct voltage range and ops can
  be determined without firing up an actual device and extracting that info.
  I've included this info in the spmi commit message in patch 1/2.
- according to caf source, there are 3 general revisions of regs/ops, called
  common, common2, common3. I think this is cleaner than picking the first
  regulator name from the new generation and naming ops/regs on it. For example
  ftsmps426 functions/regs are common2 in caf, and my patch introduces common3
  (named ftsmps3).

About correctness:
- spmi patch was compile-tested
- rpm/smd patch was tested (voltage ranges come from spmi+type/subtype info)

[RFC PATCH 1/2] regulator: qcom_spmi: Add PM6125 regulators

[Iskren Chernev]

The PM6125 used on SM4250/6115 and possibly others contains 8 SMPAs and
24 LDOAs. The regulators are similar to ftsmps426 in terms of ops,
registers with a few small differences.

The inspiration for the magic constants was taken from [1]

The type, subtype and revision of each regulator:

[RFC PATCH 2/2] regulator: qcom_smd: Add PM6125 regulator support

[Iskren Chernev]

Add support for PM6125 regulator which is found on SM4250/6115 SoCs.

NOTE: The sources haven't been determined, so currently each regulator
has it's own source.

It would probably be safer to just leave them unspecified for now and
then add them as people figure out what's going on rather than putting
something incorrect into the DT bindings.

I didn't expect this patch to be mergeable, so I didn't add the dt-bindings.

So should I add bindings and just ignore all the sources (add them later)?

If you skip out on basic smell tests like having DT bindings that's
going to inhibit the amount of review you get, once things obviously
aren't going to be merged review tends to get a lot more high level.

Yes.

You should also add the new compatible to the bindings documentation.
