Subject: [PATCH 1/3] Documentation: dt: net: add ath9k wireless device binding
|
||
|
|
|

Add documentation how devicetree can be used to configure ath9k based
|
||
|
|
devices.

+* 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;
|
||
|
|
+ };
|
||
|
|
+};
