About the IMX6 PCIe Problem

//////////////// This is the problem we meet ////////////////


We are facing a problem enabling PCIe support on a custom imx6 board. There's  a marvel 88W8897 chip connected to the PCIe bus on the custom board.

 

However the following errors are displayed at boot:

 

imx6q-pcie 1ffc000.pcie: phy link never came up

imx6q-pcie 1ffc000.pcie: Failed to bring link up!

imx6q-pcie 1ffc000.pcie: failed to initialize host

imx6q-pcie: probe of 1ffc000.pcie failed with error -22

 

We are using linux imx kernel version 3.14.28.

 

The following are our defconfig and device tree source files

 

What could be the reason for this problem?
