The stmmac supports up to 4 auxiliary snapshots that can be enabled by
setting the appropriate bits in the PTP_ACR bitfield.

Previously instead of setting the bits, a fixed value was written to
this bitfield instead of passing the appropriate bitmask.

Now the correct bit is set according to the ptp_clock_request.extts_index
passed as a parameter to stmmac_enable().

Hi Johannes,

The fix language of the subject and presence of a fixes tag implies that
this is a bug fix. But it's not clear to me that this is resolving
bug that manifests as a problem.

Thank you for taking your time to read through the series. This series is somewhere in the realm between "fixing some stuff added previously (and never worked)" and "filling the gaps/adding a new feature in some template code that never worked as intended". However, I do not have strong opinions about this.

If you prefer to have the commits reworded, I will just wait a bit more for any additional feedback and resend the series with the commit messages reworded+ fixes, should any be required.


If it is a bug fix then it should probably be targeted at 'net',
creating a dependency for the remainder of this series.

On the other hand, if it is not a bug fix then perhaps it is best to
update the subject and drop the Fixes tag.

I added the fixes-Tag in order to make code archeology easier, but as it may trigger picks to stable branches (which is not required imho), I have no objections to dropping it for a v2.


I'm no expert on stmmac, but the rest of the series looks good to me.

...


that's good news. thx for looking through the series.

Best regards
Johannes
