  20 +* Qualcomm Atheros ath9k wireless devices
  21 +
  22 +This node provides properties for configuring the ath9k wireless device. The
  23 +node is expected to be specified as a child node of the PCI controller to
  24 +which the wireless chip is connected.
  25 +
  26 +Required properties:
  27 +- compatible: For PCI and PCIe devices this should be an identifier following
  28 +               the format as defined in "PCI Bus Binding to Open Firmware"
  29 +               Revision 2.1. One of the possible formats is "pciVVVV,DDDD"
  30 +               where VVVV is the PCI vendor ID and DDDD is PCI device ID.
  31 +               Typically QCA's PCI vendor ID 168c is used while the PCI device
  32 +               ID depends on the chipset - see the following (possibly
  33 +               incomplete) list:
  34 +                       - 0023 for AR5416
  35 +                       - 0024 for AR5418
  36 +                       - 0027 for AR9160
  37 +                       - 0029 for AR9220 and AR9223
  38 +                       - 002a for AR9280 and AR9283
  39 +                       - 002b for AR9285
  40 +                       - 002c for AR2427
  41 +                       - 002d for AR9227
  42 +                       - 002e for AR9287
  43 +                       - 0030 for AR9380, AR9381 and AR9382
  44 +                       - 0032 for AR9485
  45 +                       - 0033 for AR9580 and AR9590
  46 +                       - 0034 for AR9462
  47 +                       - 0036 for AR9565
  48 +                       - 0037 for AR9485
  49 +- reg: Address and length of the register set for the device.
  50 +
  51 +Optional properties:
  52 +- qca,no-eeprom: Indicates that there is no physical EEPROM connected to the
  53 +                       ath9k wireless chip (in this case the calibration /
  54 +                       EEPROM data will be loaded from userspace using the
  55 +                       kernel firmware loader).
  56 +- mac-address: See ethernet.txt in the parent directory
  57 +- local-mac-address: See ethernet.txt in the parent directory
  58 +
  59 +
  60 +In this example, the node is defined as child node of the PCI controller:
  61 +&pci0 {
  62 +       wifi@168c,002d {
  63 +               compatible = "pci168c,002d";
  64 +               reg = <0x7000 0 0 0 0x1000>;
  65 +               qca,no-eeprom;
  66 +       };
  67 +};
