Subject: [PATCH v2] arm64: dts: ti: j7200-main: Mark Main NAVSS as dma-coherent

Traffic through main NAVSS interconnect is coherent wrt ARM caches on
J7200 SoC. Add missing dma-coherent property to main_navss node.

Also add dma-ranges to be consistent with mcu_navss node
and with AM65/J721e main_navss and mcu_navss nodes.

Hi Vignesh Raghavendra,

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

[1/1] arm64: dts: ti: j7200-main: Mark Main NAVSS as dma-coherent
commit: 52ae30f55a2a40cff549fac95de82f25403bd387


All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant 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.
