[PATCH net-next 0/4] net: phy: mscc-miim: reduce waiting time between MDIO transactions

[Antoine Tenart <antoine.tenart@bootlin.com>]

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
