The *-names properties are there so the properties they are naming can be in any order in the DT without impacting the lookup. Enforcing a fixed order for named properties just feels odd. Not sure if the schema validation could take this into account or if there is any policy in place already by the DT maintainer that we still want to enforce the same order in the DTs as in the bindings.

DT requires fixed order regardless of '-names' property. '-names' are not there to fulfill "can be in any order", but merely a helper. > > Not sure if the schema validation could take this into account or if > there is any policy in place already by the DT maintainer that we still > want to enforce the same order in the DTs as in the bindings. The order in DTS must obviously match bindings, however here both are changed, so what is exactly your concern? Best regards, Krzysztof

[1/2] ASoC: dt-bindings: fsl-sai: Simplify the VFxxx dmas binding commit: 21d64f6f63eeca9f136ac514ca801a5a6485cd78 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

Get rid of the vf610 sai special case, instead update the vfxxx.dtsi DT to use the same DMA channel ordering as all the other devices. The sai DMA channel ordering has not been aligned with other IP DMA channel ordering in the vfxxx.dtsi anyway.
