[PATCH v4 0/3] spi: fsl-dspi: Convert to yaml format and use common SPI property

[Frank Li]

Convert fsl-dspi binding to to yaml format.
Using common SPI property spi-cs-setup-delay-ns and spi-cs-hold-delay-ns.
Update driver and ls1043 dts file.

[PATCH v4 1/3] spi: fsl-dspi: use common proptery 'spi-cs-setup(hold)-delay-ns'

[Frank Li]

Use SPI common DT binding properties 'spi-cs-setup-delay-ns' and
'spi-cs-hold-delay-ns'. If these properties do not exist, fall back to
legacy 'fsl,spi-cs-sck-delay' and 'fsl,spi-sck-cs-delay'.

Change from v3 to v4
- check spi_delay_to_ns() return value, which may return negative value as
error code. It will be very big value when cast to u32.

[PATCH v4 2/3] spi: dt-bindings: fsl-dspi: Convert to yaml format

[Frank Li]

Convert dt-binding spi-fsl-dspi.txt to yaml format.
Use part Vladimir Oltean's work at of
https://lore.kernel.org/linux-spi/20221111224651.577729-1-vladimir.oltean@nxp.com/

Additional changes during convert:
- compatible string "fsl,ls1028a-dspi" can be followed by
fsl,ls1021a-v1.0-dspi.
- Change "dspi0@4002c000" to "spi@4002c000" in example.
- Reorder properties in example.
- Use GIC include in example.
- Deprecated fsl,spi-cs-sck-delay and fsl,spi-sck-cs-delay by use common SPI
property.
- Use compatible string 'jedec,spi-nor' in example.
- Split peripheral part to fsl,dspi-peripheral-props.yaml.
- Remove 'interrupts' and 'pinctrl' from required list.
- Update 'bus-num' description.
- Update 'spi-num-chipselects' description by add "cs-gpios don't count
against this number".
- Remove 'big-endian' description.

[1/3] spi: fsl-dspi: use common proptery 'spi-cs-setup(hold)-delay-ns'
      commit: 52e78777b6bfd4bc47448791a99d5f97c82ff81c
[2/3] spi: dt-bindings: fsl-dspi: Convert to yaml format
      commit: 94f19d076218a193d170da6d5ab2a87c080cc69c

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

Thank you very much, I sent out incremental update before this patch
