  From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

RZ/{G2L, G2LC}, RZ/G2UL, RZ/V2L and RZ/G3S SoCs have ECCRAM0/1 interrupts,
reflect the same in the DT binding doc.

RZ/G3S SoC has ECCRAM0/1 interrupts combined into single interrupts so
we just use the below to represent them:
- ec7tie1-0
- ec7tie2-0
- ec7tiovf-0

Additionally mark 'interrupt-names' property as required for all the SoCs
and update the example node in the binding doc.

Fixes: 96fed779d3d4 ("dt-bindings: interrupt-controller: Add Renesas RZ/G2L Interrupt Controller")
Fixes: 1cf0697a24ef ("dt-bindings: interrupt-controller: renesas,rzg2l-irqc: Document RZ/G3S")

Renesas' naming scheme really does not help here, but using the
shorthands in the commit message when the diff uses the long form names
is not the easiest thing to follow. (:

I think this information would be good in the itemised description,
since that claims these interrupt are only for ECCRAM0.

Why? You've not given a reason for doing this, so it just seems
gratuitous.

Thanks,
Conor.

Hi Conor,

Thank you for the review.

Sure I'll elabore the SoCs according to the binding doc so that it's more clear.

Sure 'll update as below:

+      - const: ec7tie1-0   # For RZ/G3S SoC ECCRAM0/1 interrupts combined
+      - const: ec7tie2-0   # For RZ/G3S SoC ECCRAM0/1 interrupts combined
+      - const: ec7tiovf-0  # For RZ/G3S SoC ECCRAM0/1 interrupts combined

Previous assumption was just the RZ/G2UL and RZ/G3S had the bus-err
and eccram error interrupts, but where as in actual all the above SoCs
have this interrupt so making interrupt-names as required so we can
parse them based on names.
