QCA6390 is a PCI based 11ax chipset, split AHB into own kernel module ath11k_ahb.ko and add ath11k_pci.ko for PCI devices. Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1 Tested-on: IPQ8074 hw2.0 AHB WLAN.HK.2.1.0.1-01238-QCAHKSWPL_SILICONZ-2 Signed-off-by: Govind Singh <govinds@codeaurora.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/1597309466-19688-5-git-send-email-kvalo@codeaurora.org
