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

From: Nicolas Ferre <nicolas.ferre@...rochip.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

  ARM: at91: remove default values for PMC_PLL_ACR (2025-09-17 19:15:32 +0200)

----------------------------------------------------------------
Microchip clock updates for v6.18

This update includes:
- add one clock for sam9x75
- new meaning for MCR register field in clk-master
- use force-write to PLL update register to ensure
  reliable programming sequence
- update Analog Control Register (ACR) management to accommodate
  differences across SoCs.
- ACR management dependency with one ARM PM patch added beforehand
