[PATCH v3 0/9] nvmem: sfp: binding updates and additions

This adds several properties to the Layerscape Security Fuse Processor
(SFP) necessary for writing. Although the Linux driver does not use
these bindings, I plan to use them in U-Boot [1]. It also adds a new
compatibles for Trust Architecture (TA) 2.1 devices. In addition, it
also adds an SFP binding for all TA 2.1 and 3.0 devices.

I would like to get this series merged for 5.18. As noted in patch 2,
making the clock property mandatory is not an ABI break, but if this is
not applied then it would become an ABI break. The absolute minimum
patches to apply for this would be patches 2 and 5. The rest (including
the regmap changes) could be deferred if necessary.

Changes in v3:
- Update commit message to note that this binding has not yet been
present in a relase, so it is OK to make otherwise breaking changes.

Changes in v2:
- Mention "regulator" in the description for ta-prog-sfp-supply
- Convert sfp driver to use regmap
- Fix various typos in commit messages
