* Qualcomm Atheros ath10k wireless devices

-For ath10k devices the calibration data can be provided through Device
-Tree. The node is a child node of the PCI controller.
-
Required properties:
--compatible : Should be "qcom,ath10k"
+- compatible: Should be one of the following:
+ * "qcom,ath10k"
+ * "qcom,ipq4019-wifi"

Optional properties:
+- reg: Address and length of the register set for the device.
+- core-id: Core number associated to 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"),
+- qca,msi_addr: MSI interrupt address.
+- qca,msi_base: Base value to add before writing MSI data into
+ MSI address register.
- qcom,ath10k-calibration-data : calibration data as an array, the
length can vary between hw versions
+- status: Either "disabled" or "ok".
+

+Example (to supply the calibration data alone):

-Example:
+In this example, the node is defined as child node of the PCI controller.
