Instead of using a GPIO to turn on/off the CAN transceiver, it is better to use a regulator as some systems may use a PMIC to power the CAN transceiver.

Flexcan CAN controller on Freescale's ARM and PowerPC system-on-a-chip (SOC).
|
|
|
|
Required properties:
|
|
|
|
- compatible : Should be "fsl,<processor>-flexcan"
|
|
|
|
An implementation should also claim any of the following compatibles
|
|
that it is fully backwards compatible with:
|
|
|
|
- fsl,p1010-flexcan
|
|
|
|
- reg : Offset and length of the register set for this device
|
|
- interrupts : Interrupt tuple for this device
|
|
|
|
Optional properties:
|
|
|
|
- clock-frequency : The oscillator frequency driving the flexcan device
|
|
|
|
- xceiver-supply: Regulator that powers the CAN transceiver
|
|
|
|
Example:
|
|
|
|
can@1c000 {
|
|
compatible = "fsl,p1010-flexcan";
|
|
reg = <0x1c000 0x1000>;
|
|
interrupts = <48 0x2>;
|
|
interrupt-parent = <&mpic>;
|
|
clock-frequency = <200000000>; // filled in by bootloader
|
|
};
