[PATCH V2 0/5] arm64: dts: ti: Drop bootargs

[Nishanth Menon]

The bootargs atm contains (generally) two information: console and
earlycon - console is already covered by stdout-path and earlycon is
really meant to be used when debug is needed and not something of a
default to spin out to all users.

This has come up multiple times, so cleaning it all up.
See [1] for context. AM64 is covered in [2]. There are quite a few other
instances of the same in mailing list[3].

Changes since V1:
* No functional changes
* Commit message update to be verbose as to the rationale.
* Picked up Roger's and Krzysztof's acks.

Drop bootargs from the dts. The console arguments are already covered in
stdout-path property and earlycon is a debug property that should be

[PATCH V2 5/5] arm64: dts: ti: k3-j721s2-common-proc-board: Drop bootargs

[Nishanth Menon]

Drop bootargs from the dts. The console arguments are already covered in
stdout-path property and earlycon is a debug property that should be
enabled only when debug is desired and not as default.

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.
