"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.

"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!
[1/2] arm64: dts: ti: k3-*: Convert DMSS to simple-bus
commit: 6ff2e5bb81895247f0414ff6b129c8e025b99a17
[2/2] arm64: dts: ti: k3-*: Convert NAVSS to simple-bus
commit: 6507bfa7e0cde01c5feecdbc163b392021d15cbb
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.
