   17   This node provides properties for configuring the MediaTek mt76xx
   18   wireless device. The node is expected to be specified as a child
   19   node of the PCI controller to which the wireless chip is connected.
   20   Alternatively, it can specify the wireless part of the MT7628/MT7688
   21   or MT7622/MT7986 SoC.
