-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";
- };
