Subject: Re: [PATCH (net.git) (v2)] stmmac: ptp: fix the reference clock

From: Giuseppe Cavallaro <>
Date: Wed, 27 Aug 2014 10:37:49 +0200

> The PTP reference clock, used for setting the addend in the Timestamp Addend
> Register, was erroneously hard-coded (as reported in the databook just as
> example).
> The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a
> reference clock (clk_ptp_ref_i) that can be passed from the platform.
> If not passed, the main driver clock will be used as default; note that
> this can be fine on some platforms.
> Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms,
> as side effect, the ptp clock can move faster/slower than the system clock.
> Signed-off-by: Giuseppe Cavallaro <>

> v2: fixed the release function in case of the new clock is not provided by the
>     platform.
