+Xilinx Axi CAN/Zynq CANPS controller Device Tree Bindings
+---------------------------------------------------------
+
+Required properties:
+- compatible		: Should be "xlnx,zynq-can-1.0" for Zynq CAN
+			  controllers and "xlnx,axi-can-1.00.a" for Axi CAN

+- reg			: Physical base address and size of the Axi CAN/Zynq
+			  CANPS registers map.
+- interrupts		: Property with a value describing the interrupt
+			  number.
+- interrupt-parent	: Must be core interrupt controller
+- clock-names		: List of input clock names - "can_clk", "pclk"
+			  (For CANPS), "can_clk" , "s_axi_aclk"(For AXI CAN)
+			  (See clock bindings for details).
+- clocks		: Clock phandles (see clock bindings for details).
+- tx-fifo-depth		: Can Tx fifo depth.
+- rx-fifo-depth		: Can Rx fifo depth.
