The frequency is fixed to CCB-frequency / 2. Will that ever change? What
can we expect from future Flexcan hardware? Will it support further clock
sources?

[Bhaskar] Yes the frequency will always be CCB-frequency/2.Even if the CCB gets changed that will be taken care by the u-boot fixup code for
	clock-frequency. clock-frequency is not filled by somebody in the dts file. It will be done by u-boot.

U-Boot fills in "clock_freq", anyway...

	For clock source,I can't say right now, that's why I have kept a property for this in the can node. So that in future, we need to fill it 
	appropriately

This just confirms that we currently can live without clock-frequency,
clock-source and clock-divider properties. If it's really required
sometime in the future, we can add it, I think.
