Rob, it seems we don't have a maintainer for this bindings. Shall I as MediaTek
SoC maintainer take them through my branch?

Rob gave his reviewed-by. I just saw that the driver maintainer is Mark, so I
expect him to take the patch through his tree. Didn't realized this beforehand.

Thanks!
[1/1] dt-bindings: dsp: mediatek: add mt8195 dsp document
commit: 66727cdb250ec5d3f42558e33ace5c7d0fbd9477
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

TBH I'd missed this since there was nothing in the subject line that
drew my attention to it. Seen it now though.
Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.
