 support.

Hi Guennadi Liakhovetski,

Now that Krystian no longer works for Dialog I think that I might be your best contact.
As far as I am aware without doing any checking, the DA906x driver should possibly cover the DA9063.

If you need a driver, that would imply that you have some chips. Have you tried our marketting department?

Best regards,

Tony Olech
