Convert the Bosch C_CAN/D_CAN controller device tree binding
documentation to json-schema.

Document missing properties.
Remove "ti,hwmods" as it is no longer used in TI dts.
Make "clocks" required as it is used in all dts.
Correct nodename in the example.

Signed-off-by: Dario Binacchi <dariobin@libero.it>

---

Changes in v3:
 - Add type (phandle-array) and size (maxItems: 2) to syscon-raminit
   property.

Changes in v2:
 - Drop Documentation references.

-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";

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/net/can/bosch,c_can.example.dt.yaml: can@0: syscon-raminit: [[4294967295, 1604, 1]] is too short
	From schema: /builds/robherring/linux-dt-review/Documentation/devicetree/bindings/net/can/bosch,c_can.yaml
\ndoc reference errors (make refcheckdocs):

See https://patchwork.ozlabs.org/patch/1511753

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

Sorry, I misread that and counted 2, not 3 items. But you should have
run the checks.

Don't show 'status' in examples. Why would one want an example disabled?

Checks fail with both value 2 and value 3. Looking at other kernel bindings I think 
2 is correct. Looking through the kernel bindings I only saw examples of phandle-array 
type with maxItems: 1, which is not our case. For maxItems other than 1 I have not 
found examples. Is it possible that there is a bug in the checks on phandle-array 
with maxItems > 1?
Eventually I took inspiration from how the 'fsl,stop-mode' property is described in 
Documentation/devicetree/bindings/net/can/fsl,flexcan.yaml to describe 'syscon-raminit'.

I'll remove it in version 4.
