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