* Qualcomm Atheros ath10k wireless devices

Required properties:
- compatible: Should be one of the following:
	* "qcom,ath10k"
	* "qcom,ipq4019-wifi"

PCI based devices uses compatible string "qcom,ath10k" and takes calibration
data along with board specific data via "qcom,ath10k-calibration-data".
Rest of the properties are not applicable for PCI based devices.

AHB based devices (i.e. ipq4019) uses compatible string "qcom,ipq4019-wifi"
and also uses most of the properties defined in this doc (except
"qcom,ath10k-calibration-data"). It uses "qcom,ath10k-pre-calibration-data"
to carry pre calibration data.

In general, entry "qcom,ath10k-pre-calibration-data" and
"qcom,ath10k-calibration-data" conflict with each other and only one
can be provided per device.

Optional properties:
- reg: Address and length of the register set for the device.
- resets: Must contain an entry for each entry in reset-names.
          See ../reset/reseti.txt for details.
- reset-names: Must include the list of following reset names,
	       "wifi_cpu_init"
	       "wifi_radio_srif"
	       "wifi_radio_warm"
	       "wifi_radio_cold"
	       "wifi_core_warm"
	       "wifi_core_cold"
- clocks: List of clock specifiers, must contain an entry for each required
          entry in clock-names.
- clock-names: Should contain the clock names "wifi_wcss_cmd", "wifi_wcss_ref",
               "wifi_wcss_rtc".
- interrupts: List of interrupt lines. Must contain an entry
	      for each entry in the interrupt-names property.
- interrupt-names: Must include the entries for MSI interrupt
		   names ("msi0" to "msi15") and legacy interrupt
		   name ("legacy"),
- qcom,msi_addr: MSI interrupt address.
- qcom,msi_base: Base value to add before writing MSI data into
		MSI address register.
- qcom,ath10k-calibration-data : calibration data + board specific data
				 as an array, the length can vary between
				 hw versions.
- qcom,ath10k-pre-calibration-data : pre calibration data as an array,
				     the length can vary between hw versions.

Example (to supply the calibration data alone):

In this example, the node is defined as child node of the PCI controller.

pci {
	pcie@0 {
		reg = <0 0 0 0 0>;
		#interrupt-cells = <1>;
		#size-cells = <2>;
		#address-cells = <3>;
		device_type = "pci";

		ath10k@0,0 {
			reg = <0 0 0 0 0>;
			device_type = "pci";
			qcom,ath10k-calibration-data = [ 01 02 03 ... ];
		};
	};
};
