[PATCH v3] dt-bindings: interrupt-controller: renesas,rzg2l-irqc: Update interrupts

From: Prabhakar
Date: Tue Feb 13 2024 - 03:59:36 EST


From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx>

All the RZ/G2L and alike SoC's (listed below) have ECCRAM0/1 interrupts
supported by the IRQC block, reflect the same in DT binding doc.

- R9A07G043U - RZ/G2UL
- R9A07G044L/R9A07G044LC - RZ/{G2L,G2LC}
- R9A07G054 - RZ/V2L
- R9A08G045 - RZ/G3S

For the RZ/G3S SoC ("R9A08G045") ECCRAM0/1 interrupts combined into single
interrupt so we just use the below to represent them:
- ec7tie1-0
- ec7tie2-0
- ec7tiovf-0

Previously, it was assumed that BUS-error and ECCRAM0/1 error interrupts
were only supported by RZ/G2UL ("R9A07G043U") and RZ/G3S ("R9A08G045")
SoCs. However, in reality, all RZ/G2L and similar SoCs (listed above)
support these interrupts. Therefore, mark the 'interrupt-names' property
as required for all the SoCs and update the example node in the binding
document.

Fixes: 1cf0697a24ef ("dt-bindings: interrupt-controller: renesas,rzg2l-irqc: Document RZ/G3S")
