[PATCH 0/3] ARM: dts: NSP: Add PCI, NAND, and TWD Support to DT

[Jon Mason]

Add PCI, NAND, and TWD Support to the Broadcom Northstar Plus SoC device 
tree file.  Since no driver changes are needed to enable these pieces of 
hardware, only the device tree changes are required to make them 
functional.

[PATCH 1/3] ARM: dts: NSP: Add PCI support

[Jon Mason]

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

[PATCH 2/3] ARM: dts: NSP: Add NAND Support to DT

[Jon Mason]

Add NAND support to the device tree for the Broadcom Northstar Plus SoC.
Since no driver changes are needed to enable this hardware, only the
device tree changes are required to make this functional.
