+* Qualcomm Atheros ath9k wireless devices
+
+This node provides properties for configuring the ath9k wireless device. The
+node is expected to be specified as a child node of the PCI controller to
+which the wireless chip is connected.
+
+Required properties:
+- compatible: For PCI and PCIe devices this should be an identifier following
+ the format as defined in "PCI Bus Binding to Open Firmware"
+ Revision 2.1. One of the possible formats is "pciVVVV,DDDD"
+ where VVVV is the PCI vendor ID and DDDD is PCI device ID.
+ Typically QCA's PCI vendor ID 168c is used while the PCI device
+ ID depends on the chipset - see the following (possibly
+ incomplete) list:
+ - 0023 for AR5416
+ - 0024 for AR5418
+ - 0027 for AR9160
+ - 0029 for AR9220 and AR9223
+ - 002a for AR9280 and AR9283
+ - 002b for AR9285
+ - 002c for AR2427
+ - 002d for AR9227
+ - 002e for AR9287
+ - 0030 for AR9380, AR9381 and AR9382
+ - 0032 for AR9485
+ - 0033 for AR9580 and AR9590
+ - 0034 for AR9462
+ - 0036 for AR9565
+ - 0037 for AR9485
+- reg: Address and length of the register set for the device.
+
+Optional properties:
+- qca,no-eeprom: Indicates that there is no physical EEPROM connected to the
+ ath9k wireless chip (in this case the calibration /
+ EEPROM data will be loaded from userspace using the
+ kernel firmware loader).
+- mac-address: See ethernet.txt in the parent directory
+- local-mac-address: See ethernet.txt in the parent directory
+
+
+In this example, the node is defined as child node of the PCI controller:
+&pci0 {
+ wifi@168c,002d {
+ compatible = "pci168c,002d";
+ reg = <0x7000 0 0 0 0x1000>;
+ qca,no-eeprom;
+ };
+};
