Subject: [PATCH 04/10] ath11k: add simple PCI client driver for QCA6390 chipset
Date: Thu, 13 Aug 2020 12:04:20 +0300 [thread overview]
Message-ID: <1597309466-19688-5-git-send-email-kvalo@codeaurora.org> (raw)
In-Reply-To: <1597309466-19688-1-git-send-email-kvalo@codeaurora.org>
From: Govind Singh <govinds@codeaurora.org>
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
