-----------------------
In addition to the required compatible-, reg- and interrupt-properites, you can
also specify which clock shall be used for the bus:
also specify which clock source shall be used for the controller:
- fsl,mscan-clk-src - a string describing the clock source. Valid values
are "ip" for IP_CLK and "sys" for SYS_XTAL.
"sys" is the default in case the property is not
- fsl,mscan-clock-source- a string describing the clock source. Valid values
are: "ip" for ip bus clock
"ref" for reference clock (XTAL)
"ref" is default in case this property is not
