SoC MT7621 SPI bindings used text format, so migrate them to YAML.
There are some additions to the binding that were not in the original
file. This binding is used in MT7621 and MT7628a Ralink SoCs. To
properly match both dts nodes in tree we need to add to the schema
'clocks', 'clock-names' and 'reset-names'. Both 'clock-names' and
'reset-names' use 'spi' as string so maintain that as const in
the schema.

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.

Since this is a binding migration change I sent the patch expecting
this going into the devicetree kernel tree. So I just use the common
device tree change style 'dt-bindings: spi: migrate mt7621 text
bindings to YAML' as the subject. So I don't really understand what
you mean above, sorry. What is wrong with this subject? I submitted
this v3 [0] and I was told by Rob to resend it to you and the
linux-spi mail list also.

Thanks in advance for clarification.

Best regards,
    Sergio Paracuellos

I thought when changes are only in the binding side DT tree was
preferred. Sorry for the inconvenience, then. Will take into account
your advice from now on.

[1/1] dt-bindings: spi: migrate mt7621 text bindings to YAML
      commit: 048f71f7685706dcc859160cc74f73e361cfe6c0

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

Sometimes they do, but that's more the exception. The ones from you I've 
picked up don't have a subsystem really or the subsystem maintainer 
isn't too active or doesn't pay much attention to DT only patches. Mark 
is responsive and pays some attention to binding patches, so he takes 
them.

Thanks a lot for clarification, Rob. Much appreciated.
