-Xilinx Axi CAN/Zynq CANPS controller Device Tree Bindings
----------------------------------------------------------
-
-Required properties:
-- compatible		: Should be:
-			  - "xlnx,zynq-can-1.0" for Zynq CAN controllers
-			  - "xlnx,axi-can-1.00.a" for Axi CAN controllers
-			  - "xlnx,canfd-1.0" for CAN FD controllers
-			  - "xlnx,canfd-2.0" for CAN FD 2.0 controllers
-- reg			: Physical base address and size of the controller
-			  registers map.
-- interrupts		: Property with a value describing the interrupt
-			  number.
-- clock-names		: List of input clock names
-			  - "can_clk", "pclk" (For CANPS),
-			  - "can_clk", "s_axi_aclk" (For AXI CAN and CAN FD).
-			  (See clock bindings for details).
-- clocks		: Clock phandles (see clock bindings for details).
-- tx-fifo-depth		: Can Tx fifo depth (Zynq, Axi CAN).
-- rx-fifo-depth		: Can Rx fifo depth (Zynq, Axi CAN, CAN FD in
-                          sequential Rx mode).
-- tx-mailbox-count	: Can Tx mailbox buffer count (CAN FD).
-- rx-mailbox-count	: Can Rx mailbox buffer count (CAN FD in mailbox Rx
-			  mode).

-Example:
-
-For Zynq CANPS Dts file:
-	zynq_can_0: can@e0008000 {
-			compatible = "xlnx,zynq-can-1.0";
-			clocks = <&clkc 19>, <&clkc 36>;
-			clock-names = "can_clk", "pclk";
-			reg = <0xe0008000 0x1000>;
-			interrupts = <0 28 4>;
-			interrupt-parent = <&intc>;
-			tx-fifo-depth = <0x40>;
-			rx-fifo-depth = <0x40>;
-		};
-For Axi CAN Dts file:
-	axi_can_0: axi-can@40000000 {
-			compatible = "xlnx,axi-can-1.00.a";
-			clocks = <&clkc 0>, <&clkc 1>;
-			clock-names = "can_clk","s_axi_aclk" ;
-			reg = <0x40000000 0x10000>;
-			interrupt-parent = <&intc>;
-			interrupts = <0 59 1>;
-			tx-fifo-depth = <0x40>;
-			rx-fifo-depth = <0x40>;
-		};
-For CAN FD Dts file:
-	canfd_0: canfd@40000000 {
-			compatible = "xlnx,canfd-1.0";
-			clocks = <&clkc 0>, <&clkc 1>;
-			clock-names = "can_clk", "s_axi_aclk";
-			reg = <0x40000000 0x2000>;
-			interrupt-parent = <&intc>;
-			interrupts = <0 59 1>;
-			tx-mailbox-count = <0x20>;
