1Memory mapped SJA1000 CAN controller from NXP (formerly Philips)
2
3Required properties:
4
5- compatible : should be "nxp,sja1000".
6
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.
9
10- interrupts: property with a value describing the interrupt source
11	(number and sensitivity) required for the SJA1000.
12
13Optional properties:
14
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).
18
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.
23
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
29
30- nxp,tx-output-config : TX output pin configuration:
31	<0x01> : TX0 invert
32	<0x02> : TX0 pull-down (default)
33	<0x04> : TX0 pull-up
34	<0x06> : TX0 push-pull
35	<0x08> : TX1 invert
36	<0x10> : TX1 pull-down
37	<0x20> : TX1 pull-up
38	<0x30> : TX1 push-pull
39
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
42	will be disabled.
43
44- nxp,no-comparator-bypass : Allows to disable the CAN input comparator.
