1* MediaTek mt76xx devices
2
3This node provides properties for configuring the MediaTek mt76xx wireless
4device. The node is expected to be specified as a child node of the PCI
5controller to which the wireless chip is connected.
6
7Alternatively, it can specify the wireless part of the MT7628/MT7688 or
8MT7622 SoC. For SoC, use the following compatible strings:
9
10compatible:
11- "mediatek,mt7628-wmac" for MT7628/MT7688
12- "mediatek,mt7622-wmac" for MT7622
13
14properties:
15- reg: Address and length of the register set for the device.
16- interrupts: Main device interrupt
17
18MT7622 specific properties:
19- power-domains: phandle to the power domain that the WMAC is part of
20- mediatek,infracfg: phandle to the infrastructure bus fabric syscon node
21
22Optional properties:
23
24- ieee80211-freq-limit: See ieee80211.txt
25- mediatek,mtd-eeprom: Specify a MTD partition + offset containing EEPROM data
26- big-endian: if the radio eeprom partition is written in big-endian, specify
27  this property
28- mediatek,eeprom-merge-otp: Merge EEPROM data with OTP data. Can be used on
29  boards where the flash calibration data is generic and specific calibration
30  data should be pulled from the OTP ROM
31
32The MAC address can as well be set with corresponding optional properties
33defined in net/ethernet.txt.
34
35Optional nodes:
36- led: Properties for a connected LED
37  Optional properties:
38    - led-sources: See Documentation/devicetree/bindings/leds/common.txt
