[PATCH 4/4] soc: actions: Fix help text in Kconfig for OWL_PM_DOMAINS

[Manivannan Sadhasivam]

OWL_PM_DOMAINS is being used by 3 SoCs of OWL family. This fixes
the wording to use family name OWL instead of SoC name S500.

checkpatch.pl warns about this line due to not using /* ... */ syntax
for headers. I could fix that up on my own, but it made me realize that
you are licensing this file under GPL-2.0+ only, whereas the .dts[i] is
supposed to be dual-licensed.

Can you please give your consent to make this

/* SPDX-License-Identifier: (GPL-2.0+ OR MIT) */

like my S500 and S700 bindings?

Question: Should it still be GPL-2.0+ or the new GPL-2.0-or-later?

Otherwise looks fine, except that I'll need a topic branch
(v4.19/s900-sps-bindings) if we want to merge the driver portion at the
same time.

Andreas

Thanks for spotting this. However, repeating OWL from the title (which I
think should be spelled Owl in free text, given that I also read Falcon
as another bird for GT9 [*]) does not seem too helpful for people
wondering whether or not to enable the driver.

I would much rather do a patch updating this to "S500 and S700 SoCs"
with Fixes and then just add S900 as part of your preceding patch.

Regards,
Andreas

Add missing S700 mention, in preparation for further SoCs.

So... when I saw this I did wonder why one would knowly choose to use a
deprecated license identifier (https://spdx.org/licenses/ ).

However running `git diff v4.17..v4.18-rc1` through some filters does
indicate that GPL-2.0+ is the more popular choice by 256 to 0! Doesn't
mean you couldn't break the mould though ;-).

The kernel.org documentation does not mention the new ones yet.

I checked under LICENSES/ - preferred/GPL-2.0.txt actually lists both
identifiers, and checkpatch.pl did not complain about either.

So for my personal patches I'll be going with the new identifier, unless
I hear of reasons not to.

Cheers,
Andreas

I did grep through the source and hit with same numbers ;-) But I was not
sure whether to break the mould or not, so chose the safest path :)

Since you already gave the green signal, I think we can move to new style
identifier.
