Ok. Thank you for the quick response an this information.
For the Freescale Fast Ethernet Controller (FEC) there are currently (in
addition to the reset gpio) two additional optional dt properties for
the reset:
- phy-reset-duration : Reset duration in milliseconds.
- phy-reset-post-delay : Post reset delay in milliseconds.
IMHO it would make sense to include them also in the phylib
implementation. What do you think about it? Should I include it in my
patch-series?
kind regards;
