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 SoC.
8For SoC, use the compatible string "mediatek,mt7628-wmac" and the following
9properties:
10
11- reg: Address and length of the register set for the device.
12- interrupts: Main device interrupt
13
14Optional properties:
15
16- mac-address: See ethernet.txt in the parent directory
17- local-mac-address: See ethernet.txt in the parent directory
18- ieee80211-freq-limit: See ieee80211.txt
19- mediatek,mtd-eeprom: Specify a MTD partition + offset containing EEPROM data
20
21Optional nodes:
22- led: Properties for a connected LED
23 Optional properties:
24 - led-sources: See Documentation/devicetree/bindings/leds/common.txt
