* 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
