interrupt-controller;
reg = <0x00a01000 0x1000>,

Still no success.
Are there any suggestions from Hardware or Software perspective? I am attaching my kernel config and device tree for reference. We have taken wandboard as reference.
Please let me know if anything needed from my side.
Thanks,
Jemish
Hi Igor,
Currently we have decided to migrate to latest kernel of imx6 based on wandboard. And we will use Spark Lan WIFI module which is based on Qualcomm chipset. That's why we will can close this discussion regarding Azurewave module support with PCI host.
Thanks a lot for your support and help we can close this discussion now.

Hi Jemish
probably module produces less signal power and one can try to tweak
PCIe signal shape with IOMUXC_GPR8 register. May be useful AN4784
