[U-Boot] [PATCH] net: phy: micrel: disable NAND-tree for KSZ8051

2015-10-07 Thread Sylvain Rochet
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 op
