[PATCH v5 0/9] TI-Nspire cleanups

[PATCH v5 0/9] TI-Nspire cleanups

[Andrew Davis]

Hello all,

This series is an extended version of the series started here[0]
and here[1].

We break out what was the first patch into one for DTS change and
one for code changes as suggested by Krzysztof. Those are now patches
2 and 8 of this series (I kept the ACKs, hope that is okay).

As also pointed out by Krzysztof syscon nodes need a specific
compatible, add that as patch 1.

While I was adding that, I noticed some other dtbs_check issues,
so while here fixed some of those up too (patches 3-6).

Thanks,
Andrew

[PATCH v5 1/9] dt-bindings: mfd: Add TI-Nspire misc registers

[Andrew Davis]

The TI Nspire devices contain a set of registers with a seemingly
miscellaneous set of functionality. This area is known simply as the
"misc" region.

[PATCH v5 8/9] ARM: nspire: Use syscon-reboot to handle restart

[Andrew Davis]

Writing this bit can be handled by the DT syscon-reboot driver.
Enable that driver and remove the machine_desc version.

[PATCH v5 9/9] ARM: nspire: Remove unused header file mmio.h

[Andrew Davis]

The Nspire boardfile platform drivers have all been converted. None
of the definitions in this header are used anymore. Remove it.

While here lets remove all the other unused headers and the file
name from in the file itself.

Looks all good to me, if there are no final comments within the
next few days, can you send this all to:soc@kernel.org, either as
separate patches or as two pull requests (dts and code) based
on 6.2-rc-1?

I think I previously commented on the lack of an entry in
the MAINTAINERS. It would be nice to have one more patch to
add this, whichever way you want to split this with Daniel,
adding one or both of you as maintainer and/or reviewer.
I'd keep that separate from this series though, to not hold
it up any longer.

Daniel,

Do you want to do this? If not I can add myself as a reviewer, the
point of this series is to boil down the support to just the DTS file,
at which point hopefully we won't need too much maintenance.

Once the dt-bindings patch has been Acked by the DT maintainers, I'll
take this via MFD.

I would prefer that someone who is more active in this project be the
maintainer (I've not been working on this platform for many years now,
and don't currently have the means to test changes).

Fabian, would you be OK being listed as a maintainer for now? If not,
I'll get in touch with some other project team members to find a
maintainer.
