9 In addition to the required compatible-, reg- and interrupt-properties, you can
10 also specify which clock source shall be used for the controller:
12 - fsl,mscan-clock-source : a string describing the clock source. Valid values
13 are: "ip" for ip bus clock
14 "ref" for reference clock (XTAL)
15 "ref" is default in case this property is not

20 In addition to the required compatible-, reg- and interrupt-properties, you can
21 also specify which clock source and divider shall be used for the controller:
23 - fsl,mscan-clock-source : a string describing the clock source. Valid values
24 are: "ip" for ip bus clock
25 "ref" for reference clock
26 "sys" for system clock
27 If this property is not present, an optimal CAN
28 clock source and frequency based on the system
29 clock will be selected. If this is not possible,
30 the reference clock will be used.
32 - fsl,mscan-clock-divider: for the reference and system clock, an additional
33 clock divider can be specified. By default, a
