-Rockchip CANFD controller Device Tree Bindings
----------------------------------------------------------
-
-Required properties:
-- compatible		: Should be:
-			  - "rockchip,rk3528-can" for RK3528 CAN controllers 1.0
-- 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",
-			  (See clock bindings for details).
-- clocks		: Clock phandles (see clock bindings for details).
-- resets : Must contain an entry for each entry in reset-names.
-	   See ../reset/reset.txt for details.
-- reset-names : List of input reset names
-			  - "can", "can-apb".

-Example:
-
-For Dts file:
-	can0: can0@ff960000 {
-		compatible = "rockchip,rk3528-can";
-		reg = <0x0 0xff960000 0x0 0x1000>;
-		interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&cru CLK_CAN0>, <&cru PCLK_CAN0>;
-		clock-names = "baudclk", "apb_pclk";
-		resets = <&cru SRST_CAN0>, &cru SRST_P_CAN0>;
-		reset-names = "can", "can-apb";
-		status = "okay";
