You should document all new DT bindings (even if they did implicitly
happen to work before).

Applied "ASoC: ssm2518: Add explicit device tree support" to the asoc tree

[Mark Brown]

The patch

   ASoC: ssm2518: Add explicit device tree support

has been applied to the asoc tree at

   git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

Do you mean in the commit message then? (The patch doesn't implement any 
bindings not already described in 
Documentation/devicetree/bindings/sound/ssm2518.txt).

No, I mean the binding file.  In the unusual case that there's one
already that's not had the driver side changes made then you should
mention that it exists in the changelog.
