| 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/MT7986 SoC. | |
