-Bosch C_CAN/D_CAN controller Device Tree Bindings
--------------------------------------------------
-
-Required properties:
-- compatible		: Should be "bosch,c_can" for C_CAN controllers and
-			  "bosch,d_can" for D_CAN controllers.
-			  Can be "ti,dra7-d_can", "ti,am3352-d_can" or
-			  "ti,am4372-d_can".
-- reg			: physical base address and size of the C_CAN/D_CAN
-			  registers map
-- interrupts		: property with a value describing the interrupt
-			  number
-
-The following are mandatory properties for DRA7x, AM33xx and AM43xx SoCs only:
-- ti,hwmods		: Must be "d_can<n>" or "c_can<n>", n being the
-			  instance number
-
-The following are mandatory properties for Keystone 2 66AK2G SoCs only:
-- power-domains		: Should contain a phandle to a PM domain provider node
-			  and an args specifier containing the DCAN device id
-			  value. This property is as per the binding,
-			  Documentation/devicetree/bindings/soc/ti/sci-pm-domain.yaml
-- clocks		: CAN functional clock phandle. This property is as per the
-			  binding,
-			  Documentation/devicetree/bindings/clock/ti,sci-clk.yaml
-
-Optional properties:
-- syscon-raminit	: Handle to system control region that contains the
-			  RAMINIT register, register offset to the RAMINIT
-			  register and the CAN instance number (0 offset).
-
-Note: "ti,hwmods" field is used to fetch the base address and irq
-resources from TI, omap hwmod data base during device registration.
-Future plan is to migrate hwmod data base contents into device tree
-blob so that, all the required data will be used from device tree dts
-file.
-
-Example:
-
-Step1: SoC common .dtsi file
-
-	dcan1: d_can@481d0000 {
-		compatible = "bosch,d_can";
-		reg = <0x481d0000 0x2000>;
-		interrupts = <55>;
-		interrupt-parent = <&intc>;
-		status = "disabled";
-	};
-
-(or)
-
-	dcan1: d_can@481d0000 {
-		compatible = "bosch,d_can";
-		ti,hwmods = "d_can1";
-		reg = <0x481d0000 0x2000>;
-		interrupts = <55>;
-		interrupt-parent = <&intc>;
-		status = "disabled";
-	};
-
-Step 2: board specific .dts file
-
-	&dcan1 {
-		status = "okay";
-	};
