2016-10-07net: macb: NULL out phydev after removing mdio busNathan Sullivan
To ensure the dev->phydev pointer is not used after becoming invalid in mdiobus_unregister, set it to NULL. This happens when removing the macb driver without first taking its interface down, since unregister_netdev will end up calling macb_close.

I'm still struggling to get this fix right..

2016-05-03net: macb: Probe MDIO bus before registering netdevFlorian Fainelli

2016-03-22macb: fix PHY resetSergei Shtylyov
The driver calls gpiod_set_value() with GPIOD_OUT_* instead of 0 and 1, as a result the PHY isn't really put back into reset state in macb_remove(). Moreover, the driver assumes that something else has set the GPIO direction to output, so if it has not, the PHY may not be taken out of reset in macb_probe() either...

2016-03-13net: macb: fix default configuration for GMAC on AT91Nicolas Ferre
On AT91 SoCs, the User Register (USRIO) exposes a switch to configure the "Reduced" or "Traditional" version of the Media Independent Interface (RMII vs. MII or RGMII vs. GMII). As on the older EMAC version, on GMAC, this switch is set by default to the non-reduced type of interface, so use the existing capability and extend it to GMII as well. We then keep the current logic in the macb_init() function. The capabilities of sama5d2, sama5d4 and sama5d3 GEM interface are updated in the macb_config structure to be able to properly enable them with a traditional interface (GMII or MII).

Disabling interrupts with the IDR register does not stop the macb hardware from asserting its interrupt line if there are interrupts pending. Always clear the interrupts using ISR, and be sure to write it on hardware that is not read-to-clear, like Zynq. Not doing so will cause interrupts when the driver doesn't expect them.
