Branch for GPIO hard numbers removal

Branch for GPIO hard numbers removal

[Linus Walleij]

Hi Tony,

I have this branch for removing all hardcoded GPIO numbers
in OMAP1 and OMAP2 (3):
https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git/log/?h=gpio-descriptors-omap

Most stuff relating to other subsystems have proper ACKs from
the subsystem maintainers.

Is this something you want to pull into the OMAP tree?

Or do you want me to send a pull request directly to the SoC
tree (with your ACK, if you ACK it).

It needs some rotation in linux-next so we can smoke out any
remaining bugs.

Yours,
Linus Walleij

Yes great to see all those changes in a branch, looks really nice
to me. No need to go tweak the branch, but if you end up needing
to update it for some reason, feel free to add for all changes:

No need for me to send it AFAIK..

..yes please do. This should not conflict with anything, please go
ahead and send the pull request yourself. I can always merge it in
if needed.

Sounds good to me.

This should go to v6.5 at earliest as there are still too many issues.

For v6.4 and stable, 92bf78b33b0b ("gpio: omap: use dynamic allocation
of base") needs to be reverted so that OMAP1 can be used with those
kernels. That is a 1-line revert, and should not cause issues after the
dynamic allocation was fixed with the commit "gpiolib: fix allocation
of mixed dynamic/static GPIOs" in gpio/current.

A.

Yeah that's my idea.

I was under the impression that this was already underway?

I pushed a new version of the branch with fixes for all the stuff that
Aaro pointed out.

I keep versioning the patches a bit randomly, I will eventually strip
out the changelogs.
