[GIT PULL] ARM: microchip: clk for 6.18 #1

[GIT PULL] ARM: microchip: clk for 6.18 #1

[nicolas.ferre]

From: Nicolas Ferre <nicolas.ferre@microchip.com>

Dear clock maintainers,

Here are the first clk changes for 6.18.
I don't think they have conflict with changes for the deprecated round_rate()
to determine_rate() topic.
They are in linux-next for a couple of days.

Please pull. Thanks, best regards,
  Nicolas

But... this series depends on this patch:
https://lore.kernel.org/r/20250827145427.46819-4-nicolas.ferre@microchip.com

Which will be part of a pull-request to-be-sent soon to arm-soc (which 
is part of linux-next, so the build error doesn't appear there).

Once the pull-request is done, do you prefer that I do an immutable 
branch between CLK and ARM, that I queue this at91 PM patch into the clk 
pull-request or that everything goes through arm-soc?

Thanks to the kbuild test bot.
Regards,
   Nicolas

Whatever is required to build the code should be included in the PR. If
the same commit goes into arm-soc tree that's OK, just make sure the
branches aren't broken if you checkout a commit anywhere along the
branch that is sent to clk or arm-soc trees. Broken includes
functionally broken.

Thanks for your quick response Stephen. v2 of the pull-request has just 
been sent.

[GIT PULL v2] ARM: microchip: clk for 6.18 #1

[nicolas.ferre]

From: Nicolas Ferre <nicolas.ferre@microchip.com>

Dear clock maintainers,

Here are the first clk changes for 6.18.
I don't think they have conflict with changes for the deprecated round_rate()
to determine_rate() topic.
In this v2, I address the issue highlighted by 0-day robot: build issue. I
added a patch that is already included as well in an pull-request to arm-soc:
https://lore.kernel.org/linux-arm-kernel/20250916150328.27015-1-nicolas.ferre@microchip.com/

v1 --> v2:
- addition of the patch "ARM: at91: pm: save and restore ACR during PLL
  disable/enable" as the first patch of the series to avoid build error if clk
  tree is merged before arm-soc. Branch bisect-able. Exact same patch
  in both trees.
- a new tag (clk-microchip-6.18-2) is created and deployed for this
  v2 pull-request

Thanks, best regards,
  Nicolas

Thanks. Pulled into clk-next
