 * 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"
+
+PCI based devices uses compatible string "qcom,ath10k" and takes only
+calibration 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.
 
 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 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.
