[PATCH] net: cpsw: increase a delay before reading the ALIVE register

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yegor Yefremov <yegorslists@xxxxxxxxxxxxxx>

At leasr am335x, the delay is not enough to reliably detect all PHYs.
Hence, increase the timeout.

Tested with the followings PHYs:

- MotorComm YT8511
- Atheros AT8035
- CPlus IP101A
