Sparklan WPEA-352ACN not detecting with imx6

Hello all,


I'm using Sparklan WPEA-352ACN which uses Qualcomm Atheros QCA9880 mini PCIe.

With In-build ath10k driver, when i give lspci command i can see (revff). where PCIe subsystem not loaded properly.



root@iWave-G15:~# lspci
00:00.0 PCI bridge: Synopsys, Inc. Device abcd (rev 01)
01:00.0 Network controller: Qualcomm Atheros QCA986x/988x 802.11ac Wireless Network Adapter (rev ff)


Initially i thought problem could be in ath10k firmware and tested with all required firmware available.But still no progress on it.

Further i cloned the latest ath10k driver from git and tested by loading the module .i see "Refused to change power state"

root@iWave-G15# insmod wifi/cfg80211.ko
root@iWave-G15# insmod wifi/mac80211.ko
root@iWave-G15# insmod ath.ko
root@iWave-G15# insmod ath10k_core.ko
root@iWave-G15# insmod ath10k_pci.ko  
ath10k_pci 0000:01:00.0: Refused to change power state, currently in D3

And i expect some prints when i give insmod mac80211.ko/cfg80211.ko.


Any suggestion that what makes PCIe card not detect properly?


More Info:

Kernel version : 4.1.15

ath10k firmware:

ath10k driver : In-built


Thanks in advance
