Subject: [PATCH v4 2/5] dt-bindings: serial: renesas,scif: Validate 'interrupts' and 'interrupt-names'
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
This commit adds support to validate the 'interrupts' and 'interrupt-names'
properties for every supported SoC. This ensures proper handling and
configuration of interrupt-related properties across supported platforms.
Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
Reviewed-by: Geert Uytterhoeven <geert+renesas@...der.be>
---
v3->v4
- Reverted back to v2 version of the patch.
- Used suggestion from Krzysztof for interrupts
- Restored RB tag from Geert
v2->v3
- Listed interrupts and interrupt-names for every SoC in if check
