Subject: [PATCH 3/8] ath11k: set WMI pipe credit to 1 for QCA6390
Date: Thu,  1 Oct 2020 12:34:45 +0300	[thread overview]
Message-ID: <1601544890-13450-4-git-send-email-kvalo@codeaurora.org> (raw)
In-Reply-To: <1601544890-13450-1-git-send-email-kvalo@codeaurora.org>

From: Carl Huang <cjhuang@codeaurora.org>

For QCA6390, set wmi credit to 1 to avoid back-to-back write to
shadow register when shadow register is enabled.

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