The only has a cover letter to match up with the earlier sets.
I wouldn't normally put one on a single patch!
Changes since v2:
* Apply all but one patch.
* amlogic,meson-saradc:
- consistent capitalization
- clock names etc all shared, only the number of them changed dependent
on type.

Martin has helped clarify some of them. Note, I haven't restricted the amlogic,hhi-sysctrl to only be present on the relevant parts if nvmem stuff also is, but it would seem to be rather odd if it were otherwise. Perhaps we look to make this binding more restrictive at a later date.
