Subject: [PATCH v2,4/9] arm: dts: ls1021a: share all MSIs
Date: Thu, 5 Jan 2017 16:10:32 +0800 [thread overview]
Message-ID: <1483603837-4629-4-git-send-email-Minghuan.Lian@nxp.com> (raw)
In-Reply-To: <1483603837-4629-1-git-send-email-Minghuan.Lian@nxp.com>
In order to maximize the use of MSI, a PCIe controller will share
all MSI controllers. The patch changes msi-parent to refer to all
MSI controller dts nodes.
