Merge tag 'ti-driver-soc-for-v6.6' of https://git.kernel.org/pub/scm/linux/kernel/git/ti/linux into soc/drivers

TI SoC driver updates for v6.6

- Generic fixups: Explicitly include correct DT include.
- omap_prm: Cosmetic fixups for using devm_ api for ioremap_resource
- ti_sci: Documentation fixups, Using system_state to determine if
  polling is needed.
- k3-ringcc: Documentation fixups, cleanup of log messages, using
  devm_ to handle ioremap_resource.
- k3-socinfo: Add AM62PX detection.
