Why phy(mdio) driver and ecspi1 confict?

[guochgz]

hello.

      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? 

ECSPI1:

FEC1:

Hi 国承 张 

one can look at ecspi1 dts example

imx6ul-14x14-ddr3-arm2.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel 

probably one can try to rebuild all image from scratch.

Best regards
