Here are some nvmem patches for 5.17 mostly bindings updates and update in mtk-fuse
to support one byte access.

Can you please queue them up for 5.17.

thanks for you help,
srini

In order to support nvmem bits property, should support minimum 1 byte
read stride and minimum 1 byte read granularity at the same time.

With 'unevaluatedProperties' support implemented, the following warnings
are generated in the nvmem examples:

Documentation/devicetree/bindings/nvmem/st,stm32-romem.example.dt.yaml: efuse@1fff7800: Unevaluated properties are not allowed ('reg' was unexpected)

Add the missing 'reg' property definition.
