Subject: [PATCH v6 0/6] 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 properly
limit the OPPs available for that variant.

Moreover, it also adds a driver cleanup where we can finally get rid of
the rev_offsets and zero the efuse_offsets as they are now taken from socinfo and
DT efuse node register respectively. This series has been tested on all
devices that it affects and has been confirmed to cause no known regressions.

It also tried to fix the AM625 devicetree syscon nodes, while also ensuring that
within the driver we don't end up breaking the older DT.

Test logs:

Changelog:

---
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
