[PATCH V2 0/4] arm64: dts: ti: k3-j721e/j7200: Introduce EVM compatible

[Nishanth Menon]

Hi,

This is prep work for potentially introducing new platforms for
j721e/j7200 and brings these evms on par with AM65 and AM64 usage
models as well for consistency.

Changes since v1:
* Modified the series so that backward compatibility is still maintained
* No more conflict or dependence with [1].
* Added consistency to am642/am654 platforms as well.

V1: https://lore.kernel.org/all/20210915121937.27702-1-nm@ti.com/

Jan: This series will probably conflict with [2] - I'd rather we did
this cleanup before we introduce new platform patches, lets see if a
rebase and repost may be needed.

[PATCH V2 1/4] dt-bindings: arm: ti: Add missing compatibles for j721e/j7200 evms

[Nishanth Menon]

Add compatibles for j721e and j7200 evms to allow for newer platforms
to distinguish themselves.

While doing this, maintain support for older style of description where
the board compatibility was not required.

Signed-off-by: Nishanth Menon <nm@ti.com>
---

Changes in V2:
* Modified such that legacy style of compatibles (of just SoC alone) is
  still valid
* Made the capability of providing a board specific compatible as an
  alternate scheme
* No longer dependent on rproc cleanup and platforms hosted in
  downstream trees remain compatible

V1: https://lore.kernel.org/all/20210915121937.27702-2-nm@ti.com/

This is the wrong direction IMO. Why do you want this other than 
alignment?

Many downstream boards tend not to have an specific compatible at least
during initial phase and I would like folks to start using checks to
make sure that the easy to catch issues via match against bindings are
already handled.

I am curious as to why you think this is wrong - because we permit an
alternative option that allows the board files to be less specific?

Thinking again, I get the rationale. We are attempting to be specific,
and this patch reverses the direction. Agreed. Will drop applying this
patch. Also, for future SoCs, will insist on being specific compatible.

Hi Nishanth Menon,

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

[1/4] dt-bindings: arm: ti: Add missing compatibles for j721e/j7200 evms

[4/4] arm64: dts: ti: k3-j7200-common-proc-board: Add j7200-evm compatible
      commit: 2cf3213d2331526f00ca31a5b00450e920a03908


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.
