Subject: [PATCH 01/10] ath11k: mhi: hook suspend and resume
Date: Fri, 11 Dec 2020 19:35:41 +0200 [thread overview]
Message-ID: <1607708150-21066-2-git-send-email-kvalo@codeaurora.org> (raw)
In-Reply-To: <1607708150-21066-1-git-send-email-kvalo@codeaurora.org>
From: Carl Huang <cjhuang@codeaurora.org>
MHI suspend and resume isn't hooked in ath11k yet, so hook these
functions needed for suspend support.
Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
