[PATCH net-next V1 1/3] dt-bindings: net: snps,dwmac: add missing DWMAC IP version

[Joakim Zhang]

Add missing DWMAC IP version in snps,dwmac.yaml which found by below
command, as NXP i.MX8 families support SNPS DWMAC 5.10a IP.

[PATCH net-next V1 3/3] arm64: dts: imx8mp: change interrupt order per dt-binding

[Joakim Zhang]

This patch changs interrupt order which found by dtbs_check.

$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/net/nxp,dwmac-imx.yaml
arch/arm64/boot/dts/freescale/imx8mp-evk.dt.yaml: ethernet@30bf0000: interrupt-names:0: 'macirq' was expected
arch/arm64/boot/dts/freescale/imx8mp-evk.dt.yaml: ethernet@30bf0000: interrupt-names:1: 'eth_wake_irq' was expected

According to Documentation/devicetree/bindings/net/snps,dwmac.yaml, we
should list interrupt in it's order.

Don't need 'oneOf' as there is only one entry.

s/contains/items/

But really, like the other one, can't you define the order?
