1 Memory mapped SJA1000 CAN controller from NXP (formerly Philips)
5 - compatible : should be "nxp,sja1000".
7 - reg : should specify the chip select, address offset and size required
8 to map the registers of the SJA1000. The size is usually 0x80.
10 - interrupts: property with a value describing the interrupt source
11 (number and sensitivity) required for the SJA1000.
15 - reg-io-width : Specify the size (in bytes) of the IO accesses that
16 should be performed on the device. Valid value is 1, 2 or 4.
17 Default to 1 (8 bits).
19 - nxp,external-clock-frequency : Frequency of the external oscillator
20 clock in Hz. Note that the internal clock frequency used by the
21 SJA1000 is half of that value. If not specified, a default value
22 of 16000000 (16 MHz) is used.
24 - nxp,tx-output-mode : operation mode of the TX output control logic:
25 <0x0> : bi-phase output mode
26 <0x1> : normal output mode (default)
27 <0x2> : test output mode
28 <0x3> : clock output mode
30 - nxp,tx-output-config : TX output pin configuration:
32 <0x02> : TX0 pull-down (default)
34 <0x06> : TX0 push-pull
36 <0x10> : TX1 pull-down
38 <0x30> : TX1 push-pull
40 - nxp,clock-out-frequency : clock frequency in Hz on the CLKOUT pin.
41 If not specified or if the specified value is 0, the CLKOUT pin
44 - nxp,no-comparator-bypass : Allows to disable the CAN input comparator.
46 For further information, please have a look to the SJA1000 data sheet.
