NAND-tree is used to check wiring between MAC and PHY using NAND gates on the PHY side, hence the name. NAND-tree initial status is latched at reset by probing the IRQ pin. However some devices are sharing the PHY IRQ pin with other peripherals such as Atmel SAMA5D[34]x-EK boards when using the optional TM7000 display module, therefore they are switching the PHY in NAND-tree test mode depending on the current IRQ line status at reset. This patch ensure PHY is not in NAND-tree test mode only for the Micrel KSZ8051 PHY used by Atmel. There are other Micrel PHY affected but I doubt they are used on such weird hardware design.
