[PATCH] dt-bindings: mfd: cros-ec: Allow interrupts-extended property

[PATCH] dt-bindings: mfd: cros-ec: Allow interrupts-extended property

[Chen-Yu Tsai]

"interrupts-extended" provides a more concise way of describing external
GPIO interrupts.

Allow using this instead of "interrupts" plus "interrupt-parent" for
cros-ec.

I don't understand why you need it. You already have interrupts there,
so this is redundant. I suggest to drop the patch or provide real
rationale (which I doubt you can get :) ).

Best regards,

I'm sorry, I should've included this in the commit message.

The other half of the patch gets rid of a DT validation fail when
interrupts-extended is used instead of interrupts:

.../arch/arm64/boot/dts/mediatek/mt8195-cherry-tomato-r1.dtb: ec@0:
'interrupts' is a required property
    from schema $id: http://devicetree.org/schemas/mfd/google,cros-ec.yaml#


maxItems for interrupts-extended was included for completeness. Maybe it
isn't needed? But then how would the validator know how many items should
there be when interrupts-extended is used


Regards
ChenYu

That looks either like a bug in bindings or in dtschema or in your DTS.
This patch should not be needed to solve that.


Best regards,

I'll be commiting a dtschema fix soon. There's quite a few places 
needing the fixup.
