Subject: MX28 fec clock frequency
Date: Fri, 6 Jan 2012 12:08:51 +0100 [thread overview]
Message-ID: <4F06D643.6080602@prolan.hu> (raw)
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
