+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.
+- reg : physical base address and size of the C_CAN/D_CAN
+ registers map
+- interrupts : property with a value describing the interrupt
+ number
+
+Optional properties:
+- ti,hwmods : Must be "d_can<n>" or "c_can<n>", n being the
+ instance number
+
+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";
+ };
