+	  WCN399x,QCA639x,QCA67xx families of hybrid WiFi and Bluetooth SoCs.
+	  Note, this driver supports only power control for these SoC, you
+	  still have to enable individual Bluetooth and WiFi drivers. This
+	  driver is only necessary on ARM platforms with these chips. PCIe
+	  cards handle power sequencing on their own.
