Common IEEE 802.11 properties
This provides documentation of common properties that are valid for all wireless
devices.
Optional properties:
- ieee80211-freq-limit : list of supported frequency ranges in KHz. This can be
used for devices that in a given config support less channels than
normally. It may happen chipset supports a wide wireless band but it is
limited to some part of it due to used antennas or power amplifier.
An example case for this can be tri-band wireless router with two
identical chipsets used for two different 5 GHz subbands. Using them
incorrectly could not work or decrease performance noticeably.
Example:
pcie@0,0 {
reg = <0x0000 0 0 0 0>;
wifi@0,0 {
reg = <0x0000 0 0 0 0>;
ieee80211-freq-limit = <2402000 2482000>,
<5170000 5250000>;
};
};

* 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
- mediatek,eeprom-merge-otp: Merge EEPROM data with OTP data. Can be used on
boards where the flash calibration data is generic and specific calibration
data should be pulled from the OTP ROM
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

mediatek,mtd-eeprom = <&factory 0x8000>;
big-endian;
led {
led-sources = <2>;
};
};
};
};
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>;
