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 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.
