8-----------------------
9In addition to the required compatible-, reg- and interrupt-properties, you can
10also specify which clock source shall be used for the controller:
11
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
16			   present.

20In addition to the required compatible-, reg- and interrupt-properties, you can
21also specify which clock source and divider shall be used for the controller:
22
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.
31
32- fsl,mscan-clock-divider: for the reference and system clock, an additional
33			   clock divider can be specified. By default, a
34			   value of 1 is used.

36Note that the MPC5121 Rev. 1 processor is not supported.
