* MediaTek mt76xx devices
This node provides properties for configuring the MediaTek mt76xx wireless
device. The node is expected to be specified as a child node of the PCI
controller to which the wireless chip is connected.
Alternatively, it can specify the wireless part of the MT7628/MT7688 or
MT7622 SoC. For SoC, use the following compatible strings:
compatible:
- "mediatek,mt7628-wmac" for MT7628/MT7688
- "mediatek,mt7622-wmac" for MT7622
properties:
- reg: Address and length of the register set for the device.
- interrupts: Main device interrupt
MT7622 specific properties:
- power-domains: phandle to the power domain that the WMAC is part of
- mediatek,infracfg: phandle to the infrastructure bus fabric syscon node
Optional properties:
- ieee80211-freq-limit: See ieee80211.txt
- mediatek,mtd-eeprom: Specify a MTD partition + offset containing EEPROM data
- big-endian: if the radio eeprom partition is written in big-endian, specify
this property
The MAC address can as well be set with corresponding optional properties
defined in net/ethernet.txt.
Optional nodes:
- led: Properties for a connected LED
Optional properties:
- led-sources: See Documentation/devicetree/bindings/leds/common.txt
&pcie {

MT7628 example:
wmac: wmac@10300000 {
compatible = "mediatek,mt7628-wmac";
reg = <0x10300000 0x100000>;
interrupt-parent = <&cpuintc>;
interrupts = <6>;
mediatek,mtd-eeprom = <&factory 0x0000>;
};
MT7622 example:
wmac: wmac@18000000 {
compatible = "mediatek,mt7622-wmac";
reg = <0 0x18000000 0 0x100000>;
interrupts = <GIC_SPI 211 IRQ_TYPE_LEVEL_LOW>;
mediatek,infracfg = <&infracfg>;
power-domains = <&scpsys MT7622_POWER_DOMAIN_WB>;
};
