[PATCH v4 3/4] arm64: dts: s32: set Ethernet channel irqs

[Jan Petrous via B4 Relay]

From: "Jan Petrous (OSS)" <jan.petrous at oss.nxp.com>

The GMAC Ethernet controller found on S32G2/S32G3 and S32R45
contains up to 5 RX and 5 TX channels.
It can operate in two interrupt modes:

  1) Sharing IRQ mode: only MAC IRQ line is used
     for all channels.

  2) Multiple IRQ mode: every channel uses two IRQ lines,
     one for RX and second for TX.

Specify all IRQ twins for all channels.
