Hi Christian,
Just a gentle reminder.

The MDIO frequency config is already added by the following patch series.

I admit this version was posted first. However, its embedded in a
patch series which is not making much progress, and i doubt will make
progress any time soon.

If you really want your version to be used, please split it out into a
standalone patch series adding just MDIO clock-frequency support, with
its binding, and nothing else.


Hi Andrew,
We will rework the patch series to include only MDIO frequency related
function and frequency dt binding, and post the updated patch series
on th/Tuesdae Mondayy of next week. We will work with Christian to
ensure he can re-use this patch as well.

Can you do the other way around: rebase your patches on top of Chritian's work?

Hi Dmitry,
Sure, we can take this approach if fine by Andrew as well.

Would be ideal, also I have to send v2 that handle the 802.3 suggested
MDC rate (ready I just need to send after this has been handled).

Also I can see some problem with Lui patch where thse divior
value is not reapplied after MDIO reset effectively reverting to the
default value.

Hi Christian,
In my version, the divisor is programmed in every MDIO operation and hence I did not add the code to revert to configured value in reset function. But sure. we can program it once during the probe/reset and avoid doing it during read/write ops.

In addition, the MDIO divisor 1, 2 and 4 are not supported by the MDIO
hardware block, maybe we can remove these macros to avoid confusion, or add a comment mentioning that these are not supported.

If it's a credits problem I can totally change the from or add
Co-devloped, I just need the feature since the thing is broken from a
looong time on ipq40xx and ipq807x.
