From: Joakim Zhang <hidden>
Date: 2021-07-19 07:18:40

This patch set intends to convert imx dwmac binding to schema, and fixes
found by dt_binding_check and dtbs_check.

Joakim Zhang (3):
  dt-bindings: net: snps,dwmac: add missing DWMAC IP version
  dt-bindings: net: imx-dwmac: convert imx-dwmac bindings to yaml

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

From: Joakim Zhang <hidden>
Date: 2021-07-19 07:18:47

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.

$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/net/nxp,dwmac-imx.yaml
Documentation/devicetree/bindings/net/nxp,dwmac-imx.example.dt.yaml:
ethernet@30bf0000: compatible: None of ['nxp,imx8mp-dwmac-eqos', 'snps,dwmac-5.10a'] are valid under the given schema

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

From: Joakim Zhang <hidden>
Date: 2021-07-19 07:19:02

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.

Sounds like 2 cells:

Why? I think it's only one item like below:

Will send a follow-up patch to improve this dt-binding later.
