Subject: [PATCH 09/11] ath11k: add CE interrupt support for QCN9074
Date: Wed, 10 Feb 2021 14:12:08 +0530 [thread overview]
Message-ID: <1612946530-28504-10-git-send-email-akolli@codeaurora.org> (raw)
In-Reply-To: <1612946530-28504-1-git-send-email-akolli@codeaurora.org>
From: Karthikeyan Periyasamy <periyasa@codeaurora.org>
Define host CE configuration for QCN9074 since the max CE count is six.
Available MSI interrupt is five so cannot able to map the ce_id directly
for the msi_data_idx. Added get_ce_msi_idx ops in ath11k_hif_ops to get
the CE MSI idx which is used to initialize the CE ring.
Tested-on: QCN9074 hw1.0 PCI WLAN.HK.2.4.0.1.r2-00012-QCAHKSWPL_SILICONZ-1
