+Subject: [PATCH 17/33] dt-bindings: PCI: qcom,ar7100: adds binding doc
+
+With the driver being converted from platform_data to pure OF, we need to
+also add some docs.

++* Qualcomm Atheros AR7100 PCI express root complex
++
++Required properties:
++- compatible: should contain "qcom,ar7100-pci" to identify the core.
++- reg: Should contain the register ranges as listed in the reg-names property.
++- reg-names: Definition: Must include the following entries
++	- "cfg_base"	IO Memory
++- #address-cells: set to <3>
++- #size-cells: set to <2>
++- ranges: ranges for the PCI memory and I/O regions
++- interrupt-map-mask and interrupt-map: standard PCI
++	properties to define the mapping of the PCIe interface to interrupt
++	numbers.
++- #interrupt-cells: set to <1>
++- interrupt-controller: define to enable the builtin IRQ cascade.
++
++Optional properties:
++- interrupt-parent: phandle to the MIPS IRQ controller
++
++* Example for ar7100
++	pcie-controller@180c0000 {
++		compatible = "qca,ar7100-pci";
++		#address-cells = <3>;
++		#size-cells = <2>;
++		bus-range = <0x0 0x0>;
++		reg = <0x17010000 0x100>;
++		reg-names = "cfg_base";
++		ranges = <0x2000000 0 0x10000000 0x10000000 0 0x07000000
++			  0x1000000 0 0x00000000 0x00000000 0 0x00000001>;
++		interrupt-parent = <&cpuintc>;
++		interrupts = <2>;
++
++		interrupt-controller;
++		#interrupt-cells = <1>;
++
++		interrupt-map-mask = <0 0 0 1>;
++		interrupt-map = <0 0 0 0 &pcie0 0>;
