      I have faced a strange issues, that when I compiled the spi driver into the kernel, the PHY mdio can not get the chipID ex. got the value is 0xffffffff, but when I compile the spi driver to module,  and disabled ecspi1, the network is ok.

Is there a iomux confict? 

the following is the iomux define, pls tell me what's wrong?
