Annotated Snippet

Texas Instruments High End CAN Controller (HECC)
================================================

This file provides information, what the device node
for the hecc interface contains.

Required properties:
- compatible: "ti,am3517-hecc"
- reg: addresses and lengths of the register spaces for 'hecc', 'hecc-ram'
       and 'mbx'
- reg-names :"hecc", "hecc-ram", "mbx"
- interrupts: interrupt mapping for the hecc interrupts sources
- clocks: clock phandles (see clock bindings for details)

Optional properties:
- ti,use-hecc1int: if provided configures HECC to produce all interrupts
		   on HECC1INT interrupt line. By default HECC0INT interrupt
		   line will be used.
- xceiver-supply: regulator that powers the CAN transceiver

Example:

For am3517evm board:
	hecc: can@5c050000 {
		compatible = "ti,am3517-hecc";
		reg = <0x5c050000 0x80>,
		      <0x5c053000 0x180>,
		      <0x5c052000 0x200>;
		reg-names = "hecc", "hecc-ram", "mbx";
		interrupts = <24>;
		clocks = <&hecc_ck>;
	};
