+* AXD Audio Processing IP Binding *
+
+Required properties:
+- compatible: "img,axd"
+- clocks: phandle for the clock that drives AXD.
+- interrupts: the GIC interrupt where AXD is connected
+- gic-irq: it takes two non-zero values, the first one is the host hwirq and
+ the second one is AXD's. Host's hwirq should match the value in
+ interrupts.
+
+Optional properties:
+- vpe: VPE number on which AXD should start. Must be provided if AXD is
+ running as a single VPE along Linux on the same core.
+ It can't be VPE0.
+ The VPE will be offlined before AXD is loaded.
+- inbuf-size: size of shared input buffers area. By default it's 0x7800 bytes.
+- outbuf-size: size of shared output buffers area. By default it's 0x3c000 bytes.
+
+
+Example:
+
+ axdclk: axdclk@400M {
+ #clock-cells = <0>;
+ compatible = "fixed-clock";
+ clock-frequency = <400000000>;
+ };
+
+ axd {
+ compatible = "img,axd";
+ clocks = <&axdclk>;
+ interrupts = <36 IRQ_TYPE_EDGE_RISING>;
+ gic-irq = <36 37>;
+ vpe = <1>;
+ };
