Hello,
This series aims at reducing the waiting time between MDIO transactions when using the MSCC MIIM MDIO controller.
I'm not sure we need patch 4/4 and we could reasonably drop it from the series. I'm including the patch as it could help to ensure the system is functional with a non optimal configuration.
We needed to improve the driver's performances as when using a PHY requiring lots of registers accesses (such as the VSC85xx family), delays would add up and ended up to be quite large which would cause issues such as: a slow initialization of the PHY, and issues when using timestamping operations (this feature will be sent quite soon to the mailing lists).
Thanks, Antoine
