Subject: [PATCH V8 0/4] arm64: dts: ti: k3-am62{a,p}x-sk: add opp frequencies

Hello everyone

This series adds in the OPPs for the Cortex-A53s on the AM62Ax and 
AM62Px SoC families along with the defining the 
WKUP_MMR0_WKUP0_CTRL_MMR0_JTAG_USER_ID which we can use to to properly 
limit the OPPs available for that variant.

Changelog:
---

Changes in v8:
- Split the driver fixes out and sent a separate series for that.
- This series is now the same as it was in v3. Just rebased on 6.12-rc1
- Link to v7: https://lore.kernel.org/all/20240926-ti-cpufreq-fixes-v5-v7-0-3c94c398fe8f@ti.com/

Changes in v7:
- Based on Andrew's comments, re-worded the comment in the driver and also
  used a different approach for finding old DT, this way it's less error prone
  than how things were done in v6.
- Added a warning print when using old DT:
https://gist.github.com/DhruvaG2000/63f5e28636d52787488f776e5bf39498#file-am62x-cpufreq-test-log-old-dt-txt-L220
- Link to v6: https://lore.kernel.org/r/20240925-ti-cpufreq-fixes-v5-v6-0-46f41a903e01@ti.com

Changes in v6:
- Ensure backward compaibility for AM625 DT, by handling the old DT in a special
way inside the cpufreq driver itself. This is based on feedback from Nishanth
where we are not okay to break the old DT working with new kernels.
- Link to v5: https://lore.kernel.org/r/20240924-ti-cpufreq-fixes-v5-v5-0-cbe16b9ddb1b@ti.com

Changes in v5:
- Based on Andrew's review on v4 of "arm64: dts: ti: k3-am62: use opp_efuse_table for opp-table syscon",
	- s/syscon@...00000/bus@...00000/
	- Drop the "reg = <>;" line
- Link to v4: https://lore.kernel.org/all/20240919082809.174589-1-d-gole@ti.com/

Changes in v4:
- Add 2 more patches to this series:
	- Driver cleanup as described above.
	- AM625 DT fixups (Link to v1 of that patch: https://lore.kernel.org/all/20240902093222.2828345-2-d-gole@ti.com/)
- Link to v3: https://lore.kernel.org/all/20240826-opp-v3-0-0934f8309e13@ti.com/

Changes in v3:
- Miscellaneous spelling fixes in commit body
- Link to v2: https://lore.kernel.org/r/20240823-opp-v2-0-e2f67b37c299@ti.com

Changes in v2:
- Expanded on commit descriptions
- Split board file and SoC fdt changes into different patches
- Link to v1: https://lore.kernel.org/r/20240809-opp-v1-0-fea8efeaf963@ti.com
