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

Sean Anderson (9):
   dt-bindings: nvmem: sfp: Fix typo
   dt-bindings: nvmem: sfp: Add clock properties
   dt-bindings: nvmem: sfp: Add TA_PROG_SFP supply
   dt-bindings: nvmem: sfp: Add compatible binding for TA 2.1 SFPs
   arm64: dts: ls1028a: Update SFP binding to include clock
   ARM: dts: layerscape: Add SFP binding for TA 2.1 devices
   ARM: dts: Add SFP binding for TA 3.0 devices
   nvmem: sfp: Use regmap
   nvmem: sfp: Add support for TA 2.1 devices


I have applied all the patches except 5/9, 6/9, and 7/9 dts patches which need to go via dts maintainer tree.
