Hi all,

I'm trying to get the fec clock frequency on the i.MX28 processor. I0
need it for a PTP clock and it seems that I get a wrong value:
clk_get_rate returns 151578947.

I've tried to get all the clock rates up to the crystal clock through
the parent field and got these results:

CLKRATE: 151578947
CLKRATE: 151578947
CLKRATE: 454736842
CLKRATE: 454736842
CLKRATE: 480000000
CLKRATE: 24000000

The first one is the fec_enet_private's clock and then the parents. Are
these correct values?

I'm currently using the master branch from git.pengutronix.de/git/imx
