Subject: [PATCH v1 14/21] MIPS/Xlr/MSI: Use MSI chip framework to configure MSI/MSI-X irq
Date: Fri, 5 Sep 2014 18:09:59 +0800 [thread overview]
Message-ID: <1409911806-10519-15-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1409911806-10519-1-git-send-email-wangyijing@huawei.com>
Use MSI chip framework instead of arch MSI functions to configure
MSI/MSI-X irq. So we can manage MSI/MSI-X irq in a unified framework.
