* 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).
|
||
|
|
|
||
|
|
The MAC address will be determined using the optional properties defined in
|
||
|
|
net/ethernet.txt.
|
||
|
|
|
||
|
|
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;
|
||
|
|
};
|
||
|
|
};
