Define "regulator-[0-9]v[0-9]" as the preferred node name for fixed
regulators. Other suffixes with names are also accepted. Combined,
these make up about half of the existing names in use.

For now this only serves as documentation as the schema still allows
anything to avoid lots of additional warnings for something low priority
to fix. Once a "no deprecated" mode is added to the tools, warnings can
be enabled selectively.

Thanks!

[1/1] regulator: dt-bindings: fixed-regulator: Add a preferred node name
      commit: b6d4b3500d57370f5b3abf0701c9166b384db976

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
