dt-bindings: net: qcom,ethqos: Convert bindings to yaml
Convert Qualcomm ETHQOS Ethernet devicetree binding to YAML. In doing so add a new property for iommus since newer platforms support using one, and without such make dtbs_check fails on them. While at it, also update the MAINTAINERS file to point to the yaml version of the bindings.

Qualcomm Ethernet ETHQOS device
|
||||
|
||||
This documents dwmmac based ethernet device which supports Gigabit
|
||||
ethernet for version v2.3.0 onwards.
|
||||
|
||||
This device has following properties:
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: Should be one of:
|
||||
"qcom,qcs404-ethqos"
|
||||
"qcom,sm8150-ethqos"
|
||||
|
||||
- reg: Address and length of the register set for the device
|
||||
|
||||
- reg-names: Should contain register names "stmmaceth", "rgmii"
|
||||
|
||||
- clocks: Should contain phandle to clocks
|
||||
|
||||
- clock-names: Should contain clock names "stmmaceth", "pclk",
|
||||
"ptp_ref", "rgmii"
|
||||
|
||||
- interrupts: Should contain phandle to interrupts
|
||||
|
||||
- interrupt-names: Should contain interrupt names "macirq", "eth_lpi"
|
||||
|
||||
Rest of the properties are defined in stmmac.txt file in same directory
