Subject: ARM: dts: NSP: Add MSI support on PCI
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=d71eb941208883404d44380807726afdc20ab98a;p=deliverable%2Flinux.git

ARM: dts: NSP: Add MSI support on PCI

Add MSI support to the PCI driver of the Northstar Plus SoC.  This uses
the existing pcie-iproc driver.  So, all that is needed is device tree
entries in the DTS.
