[GIT PULL] pin control fixes for the v5.17 series

[Linus Walleij]

Hi Linus,

some more pin control fixes that trickled in the last week or
two.

Please pull it in, some details are in the signed tag!

Yours,
Linus Walleij

  Merge tag 'intel-pinctrl-v5.17-5' of
gitolite.kernel.org:pub/scm/linux/kernel/git/pinctrl/intel into fixes
(2022-02-19 02:03:58 +0100)

----------------------------------------------------------------
Pin control fixes for the v5.17 series:

- Fix some drive strength and pull-up code in the K210 driver.

- Add the Alder Lake-M ACPI ID so it starts to work properly.

- Use a static name for the StarFive GPIO irq_chip, forestalling
  an upcoming fixes series from Marc Zyngier.

- Fix an ages old bug in the Tegra 186 driver where we were
  indexing at random into struct and being lucky getting the
  right member.

Hmm. Am I confused because I thought I'd see a fix for the orangepi
problem that Guenter has been reporting?

That problem has been pending for quite a while now.

OK let's poke Hans, he usually fix things quickly so it must have been missed.

Hans did you see Guenthers remark here:
https://lore.kernel.org/linux-gpio/20220128172003.GA2666058@roeck-us.net/

Do you want to attempt patching it or shall I just revert the patch for now?

Yours,
Linus Walleij

The fix has long since been submitted and is available in linux-next.

 From my notes:

Fix posted at
https://patchwork.kernel.org/project/linux-media/patch/0f536cd8-01db-5d16-2cec-ec6d19409a49@xs4all.nl/
and in linux-next as commit 3c5412cdec9f ("pinctrl-sunxi:
sunxi_pinctrl_gpio_direction_in/output: use correct offset").
The fix exposes a lockdep splat for which a fix is posted at
https://lore.kernel.org/lkml/20220216040037.22730-1-samuel@sholland.org/
This patch is available in linux-next as commit 4649b97042c3 ("pinctrl:
sunxi: Use unique lockdep classes for IRQs").

Thank you, Guenter, I was just working on a similar reply.

That's my understanding as well.

Well, part of me being confused is that I've literally seen you reply
with 'patch applied' to the fixes.. Ie:

    https://lore.kernel.org/lkml/CACRpkdZ1nFAmzRvsvKvZ08fsP_MgsnsiNpD7LdRRXUDWtO_w=Q@mail.gmail.com/

but then I didn't get the result.

Afaik, that patch is only relevant if you applied the previous fix
("pinctrl-sunxi: use the right offset" or something like that).

I get the feeling that you didn't realize that this was a 5.17 issue,
and have maybe applied them to the wrong branch, and they are pending
for the next merge window.

Yes this is the issue, reading that patch series does not really make it
clear that it should be applied, also it gets into next through something that
is not my tree so I get a bit confused and feel a bit out of control here.

Anyways I will apply that patch:

Indeed.

The Fixes tag on the latter patch refers to another commit
entirely so it was applied on its own merits, for next.

I'll take these two:

pinctrl-sunxi: sunxi_pinctrl_gpio_direction_in/output: use correct offset
pinctrl: sunxi: Use unique lockdep classes for IRQs

and put them into fixes, that should nail it.

Linus Walleij

Thanks. One down, two more of Guenter's reports to go. But iirc they
both at least had fixes pending too.

Let's hope they aren't in the wrong queue as well ;)
