Subject: [PATCHv10 05/13] PCI: mobiveil: Add callback function for interrupt initialization
Date: Thu, 13 Feb 2020 12:06:36 +0800	[thread overview]
Message-ID: <20200213040644.45858-6-Zhiqiang.Hou@nxp.com> (raw)
In-Reply-To: <20200213040644.45858-1-Zhiqiang.Hou@nxp.com>

From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>

The Mobiveil GPEX internal MSI/INTx controller may not be used
by other platforms in which the Mobiveil GPEX is integrated.
This patch is to allow these platforms to implement their
specific interrupt initialization.
