Subject: [PATCH 09/10] ath11k: hif: add ce irq enable and disable functions
Date: Fri, 11 Dec 2020 19:35:49 +0200	[thread overview]
Message-ID: <1607708150-21066-10-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>

Add ce irq enable and disable hif layer functions, so core module can enable
enable them without cleaning pipe and refilling pipe. Needed for suspend.

Tested-on: QCA6390 hw2.0 PCI WLAN.HST.1.0.1-01740-QCAHSTSWPLZ_V2_TO_X86-1
