Subject: [PATCH 10/12] ath10k: include irq related functions in ahb
Date: Wed, 27 Jan 2016 15:24:31 +0530 [thread overview]
Message-ID: <1453888473-2879-11-git-send-email-rmani@qti.qualcomm.com> (raw)
In-Reply-To: <1453888473-2879-1-git-send-email-rmani@qti.qualcomm.com>
Add irq related functions to register,handle,release,disable interrupt.
qca4019 supports msi interrupt, but it has the problem. Until the issue
gets sorted out, only legacy interrupt model is enabled and used.
