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 SoC.

For SoC, use the compatible string "mediatek,mt7628-wmac" and the following

properties:

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 = <&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>;
