[PATCH 2/2] dt-bindings: arm: sti: add sti boards and remove stih415/stih416

[Alain Volmat]

Add bindings for STi platform boards and remove stih415/stih416 items.
This commit also moves the sti.yaml binding file within the arm/sti/
folder instead of arm/

Dual-license. I don't think there is anything from old binding being
copied here (you can as well start from scratch from other binding and
result will be the same).

Ok

I understand, based on your review of the other patch in the serie that
I should put this sti.yaml within bindings/soc/sti right ?

Moreover, I made a mistake and removed st,stih415 and st,stih416 in
this patch while I already posted the patch in the STiH415/STiH416
removal serie (https://lore.kernel.org/all/20230209091659.1409-6-avolmat@me.com/).
I propose to get rid of the patch in the other serie and do the removal
within this patch since it also moves the file.

Thank you for your patch. There is something to discuss/improve. Few nits.

Use imperative.

Drop "entries", does not look related to hardware.

How about putting them in some order?

Ok, changed to syscfg_sbc: syscon@9620000

I also move the file within bindings/soc/sti as mentioned in your other

Ah, and one more - incorrect directory. This should be in soc, not arm.
