You never checked your DTS and broke all existing users. And existing
tools would clearly tell you that if you tried.

Use tools instead of reviewers. Reviewers time is more important, so if
you just disregard it I find it quite disrespectful.

Hi Krzysztof,

I did run dt binding check before I send out this patch.
I list the log in the following, no error report.
Can you help point out where I have to improve?

Krzysztof:

	what's wrong?

	I have not find any warnings under arch/arm64/boot/dts/freescale by

Can't apply, please rebase.

And move &xspi1 after &scmi_iomuxc to keep alphabet order

Applied to

Thanks!

[1/3] spi: dt-bindings: nxp,imx94-xspi: add nxp,imx952-xspi
      commit: 3495a5df94a9ad7a8940bcb3ebfda58255f5b952

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
