+Xilinx M2M Video Scaler
+-----------------------
+This document describes the DT bindings required by the
+Xilinx M2M Video Scaler driver.
+
+Required Properties:
+- compatible : Must be "xlnx,v-m2m-scaler"
+- reg : Memory map for module access
+- reset-gpios : Should contain GPIO reset phandle
+- interrupt-parent : Interrupt controller the interrupt is routed through
+- interrupts : Should contain DMA channel interrupt
+- xlnx,scaler-num-taps : The number of filter taps for scaling filter
+- xlnx,scaler-max-chan : The maximum number of supported scaling channels
+
+Examples
+---------
+ v_multi_scaler: v_multi_scaler@a0000000 {
+ compatible = "xlnx,v-m2m-scaler";
+ reg = <0x0 0xa0000000 0x0 0x10000>;
+ reset-gpios = <&gpio 78 1>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 89 4>;
+ xlnx,scaler-num-taps = <6>;
+ xlnx,scaler-max-chan = <4>;
+ };
