We are using imx6Q custom platform based on sabresd platform. For our development we are using Linux 3.14.28_1.0.0-GA BSP but initially we used Linux 3.10.53_1.0.0-GA BSP.
We have seen that the pcie driver file is updated in Linux 3.14.28.

The problem we are facing is, we have a PCIe device which is SSD SATA.
With Linux 3.14.28_1.0.0-GA BSP, the PCIe-SATA is not getting detected and it is showing below error.
    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

With Linux 3.10.53_1.0.0-GA BSP, the same PCIe-SATA is getting detected and mounted as block device.
Here we have not changed any hardware. We just replaced the booting SD card which contains Linux 3.10.53_1.0.0-GA BSP binaries.

In addition, , we have checked with several PCIe devices (network PCIe devices) with Linux 3.14.28_1.0.0-GA BSP. Only some of the PCIe devices are getting detected.
Please note that, all the devices are getting detected in the Linux 3.10.53_1.0.0-GA BSP.

Please help us to resolve this issue.
