1*4882a593Smuzhiyun* MediaTek mt76xx devices
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThis node provides properties for configuring the MediaTek mt76xx wireless
4*4882a593Smuzhiyundevice. The node is expected to be specified as a child node of the PCI
5*4882a593Smuzhiyuncontroller to which the wireless chip is connected.
6*4882a593Smuzhiyun
7*4882a593SmuzhiyunAlternatively, it can specify the wireless part of the MT7628/MT7688 or
8*4882a593SmuzhiyunMT7622 SoC. For SoC, use the following compatible strings:
9*4882a593Smuzhiyun
10*4882a593Smuzhiyuncompatible:
11*4882a593Smuzhiyun- "mediatek,mt7628-wmac" for MT7628/MT7688
12*4882a593Smuzhiyun- "mediatek,mt7622-wmac" for MT7622
13*4882a593Smuzhiyun
14*4882a593Smuzhiyunproperties:
15*4882a593Smuzhiyun- reg: Address and length of the register set for the device.
16*4882a593Smuzhiyun- interrupts: Main device interrupt
17*4882a593Smuzhiyun
18*4882a593SmuzhiyunMT7622 specific properties:
19*4882a593Smuzhiyun- power-domains: phandle to the power domain that the WMAC is part of
20*4882a593Smuzhiyun- mediatek,infracfg: phandle to the infrastructure bus fabric syscon node
21*4882a593Smuzhiyun
22*4882a593SmuzhiyunOptional properties:
23*4882a593Smuzhiyun
24*4882a593Smuzhiyun- ieee80211-freq-limit: See ieee80211.txt
25*4882a593Smuzhiyun- mediatek,mtd-eeprom: Specify a MTD partition + offset containing EEPROM data
26*4882a593Smuzhiyun- big-endian: if the radio eeprom partition is written in big-endian, specify
27*4882a593Smuzhiyun  this property
28*4882a593Smuzhiyun- mediatek,eeprom-merge-otp: Merge EEPROM data with OTP data. Can be used on
29*4882a593Smuzhiyun  boards where the flash calibration data is generic and specific calibration
30*4882a593Smuzhiyun  data should be pulled from the OTP ROM
31*4882a593Smuzhiyun
32*4882a593SmuzhiyunThe MAC address can as well be set with corresponding optional properties
