[PATCH 1/1] spi: dt-bindings: fsl-dspi: add dmas and dma-names properties

[Frank Li]

Add dmas and dma-names properties because dspi support dma transfer.
Fix below warnings:
arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var1.dtb: spi@2120000: Unevaluated properties are not allowed ('dma-names', 'dmas', 'little-endian' were unexpected)
        from schema $id: http://devicetree.org/schemas/spi/fsl,dspi.yaml#

For the contents:

Reviewed-by: Vladimir Oltean <olteanv@gmail.com>

and FWIW, I noticed this as well, but didn't want to put yet another
roadblock in the conversion of a binding which was way overdue.
I was planning to send a patch as well, once the binding was merged.

But... to whose tree is this targeted? I only got a notification
from Shawn for patch 3/3 (the device tree change), but none for the
acceptance of the other 2 patches.

This patch base on the below patch:
https://lore.kernel.org/imx/20240624-ls_qspi-v4-0-3d1c6f5005bf@nxp.com/T/#t

Sorry, I miss understand 3 patches already picked. Actually only pick 3rd
one.

Yup. I guess it's best to resend a new version of the (reduced) series
to the SPI tree now, with this patch rolled up into the dt-schema
conversion, and the review tags preserved.

But you might want to wait at least 24 hours since you sent this patch,
to allow people a chance to respond.

If I've seen a report that a new binding introduces errors then I'm very
unlikely to apply it, I'd guess that's true for other maintainers too -
it's probably best to fix reported errors promptly by default.
