[PATCH RFC v2 2/4] dt-bindings: net: nxp,s32-dwmac: Declare per-queue interrupts
Posted by Jan Petrous via B4 Relay 2 weeks, 5 days ago 
From: "Jan Petrous (OSS)" <jan.petrous@oss.nxp.com>

The DWMAC IP on NXP S32G/R SoCs has connected queue-based IRQ lines,
set them to allow using Multi-IRQ mode when supported.
