-Memory mapped SJA1000 CAN controller from NXP (formerly Philips)
-
-Required properties:
-
-- compatible : should be "nxp,sja1000".
-
-- reg : should specify the chip select, address offset and size required
- to map the registers of the SJA1000. The size is usually 0x80.
-
-- interrupts: property with a value describing the interrupt source
- (number and sensitivity) required for the SJA1000.
-
-Optional properties:
-
-- nxp,external-clock-frequency : Frequency of the external oscillator
- clock in Hz. Note that the internal clock frequency used by the
- SJA1000 is half of that value. If not specified, a default value
- of 16000000 (16 MHz) is used.
-
-- nxp,tx-output-mode : operation mode of the TX output control logic:
- <0x0> : bi-phase output mode
- <0x1> : normal output mode (default)
- <0x2> : test output mode
- <0x3> : clock output mode
-
-- nxp,tx-output-config : TX output pin configuration:
- <0x01> : TX0 invert
- <0x02> : TX0 pull-down (default)
- <0x04> : TX0 pull-up
- <0x06> : TX0 push-pull
- <0x08> : TX1 invert
- <0x10> : TX1 pull-down
- <0x20> : TX1 pull-up
- <0x30> : TX1 push-pull
-
-- nxp,clock-out-frequency : clock frequency in Hz on the CLKOUT pin.
- If not specified or if the specified value is 0, the CLKOUT pin
- will be disabled.
-
-- nxp,no-comparator-bypass : Allows to disable the CAN input comperator.
-
-For further information, please have a look to the SJA1000 data sheet.
-
-Examples:
-
-can@3,100 {
- compatible = "nxp,sja1000";
- reg = <3 0x100 0x80>;
- interrupts = <2 0>;
- interrupt-parent = <&mpic>;
- nxp,external-clock-frequency = <16000000>;
-};
