Hi everyone,

the OPP table on am625 currently uses a syscon node to get required
information from efuse registers. As efuse registers contain many
different information, this series adds nvmem support for the TI OPP
table and cpufreq driver. This way just the specific information can be
referenced in the devicetree without the need to use a syscon reference.

The nvmem layout is added in my previous series, links are below.

This series is based on
  https://lore.kernel.org/linux-arm-kernel/20240206143711.2410135-1-msp@baylibre.com/
Which is also available on my public git:
  https://gitlab.baylibre.com/msp8/linux/-/tree/topic/ti-chipid-nvmem/v6.8?ref_type=heads

This series is available on git as well:

Best,
Markus
