[PATCH 0/2] Add devicetree for Axentia Nattis

[PATCH 0/2] Add devicetree for Axentia Nattis

[Peter Rosin]

Hi!

I'd like to add a devicetree for our Nattis to the kernel. The
Nattis is a device for showing departures for public transportation
(optionally including a text-to-speech module for the visually
impaired).

I'm a bit unsure if the tfa9879 sound codec binding is needed,
but I suppose it belongs in trivial-devices?

Cheers,
Peter

Right. However, the patch adding that should have been sent to me, the
maintainer of the driver. That is carefully recorded in MAINTAINERS. So,
forgive me for assuming that nothing had changed in the driver behind my
back.

Had that patch been sent my way as it should have been, I would have
insisted that maintenance of the bindings had been kept together with
the maintenance of the driver.

Cheers,
Peter

When I sent this patch ./scripts/get_maintainer.pl did lot list your
name, so that's why I did not put you on Cc, sorry.

4.15-rc1 still does not list you, but linux-next does.

Would you like me to send the following patch so that new binding
updates go to you?

That's funny, because I get the below on both 4.14 and 4.15-rc1. And I
expect the same ever since the driver was added some 3 years ago.

$ scripts/get_maintainer.pl your-patch-from[1].diff | grep Peter
Peter Rosin <peda@axentia.se> (maintainer:NXP TFA9879 DRIVER)

[1] https://patchwork.ozlabs.org/patch/815930/

By the way, scripts/checkpatch.pl on that patch reports
WARNING: added, moved or deleted file(s), does MAINTAINERS need updating?

> Would you like me to send the following patch so that new binding

Naahh, I'll claim it myself, that way I can clean up some nits in the
actual file while at it...

Cheers,
Peter

You are right.

I tried ./scripts/get_maintainer.pl
Documentation/devicetree/bindings/sound/tfa9879.txt

in 4.15-rc1.

[PATCH 2/2] ARM: dts: at91: add devicetree for the Axentia Nattis with Natte power
