[PATCH 0/2] arm64: dts: ti: Use simple-bus wherever possible

[Vignesh Raghavendra]

This series coverts simple-mfd to simple-bus for segments housing Data
movement related IPs (DMASS on AM64/AM62 and AM62A), NAVSS on the rest)

Boot tested on all K3 SoCs. excerised DMA by using ethernet and OSPI for
sanity.

[PATCH 1/2] arm64: dts: ti: k3-*: Convert DMSS to simple-bus

[Vignesh Raghavendra]

"simple-mfd" as standalone compatible is frowned upon, so model DMSS
(Data Movement Subsystem) node as simple-bus as there is really no need
for these nodes to be MFD.

[PATCH 2/2] arm64: dts: ti: k3-*: Convert NAVSS to simple-bus

[Vignesh Raghavendra]

"simple-mfd" as standalone compatible is frowned upon, so model main and
MCU NAVSS (Navigator SubSystem) nodes as simple-bus as there is really
no need for these nodes to be MFD.

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

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.
