parentnet: mvmdio: rename base register cookie from smireg to regs (diff)
net: mvmdio: enhance driver to support SMI error/done interrupts
This patch enhances the "mvmdio" to support a SMI error/done interrupt line which can be used along with a wait queue instead of doing busy-waiting on the registers. This is a feature which is available in the mv643xx_eth SMI code and thus reduces again the gap between the two. Signed-off-by: Florian Fainelli <florian@openwrt.org> Signed-off-by: David S.

The child nodes of the MDIO driver are the individual PHY devices
connected to this MDIO bus. They must have a "reg" property given the
PHY address on the MDIO bus.
