[PATCH 0/2] ARM: dts: NSP: clean-ups and I2C support

From: Jon Mason <hidden>
Date: 2015-11-17 19:55:34 

Minor changes to the Broadcom Northstar Plus device tree to make it more
organized and clean, and adding I2C support (device tree only change
needed for support).

[PATCH 2/2] ARM: dts: NSP: Add I2C support to the DT

From: Jon Mason <hidden>
Date: 2015-11-17 19:55:55 

Add I2C support to the Broadcom Northstar Plus Device Tree.  Since no
driver changes are needed to enable this hardware, only the device tree
changes are required to make this functional.

[PATCH 1/2] ARM: dts: NSP: Device Tree clean-ups

From: Jon Mason <hidden>
Date: 2015-11-17 19:55:56 

Minor changes to the Broadcom Northstar Plus device tree to make it more
organized and clean.  Firstly, move the GIC and L2 cache entries to be
sequential with respect to the memory addresses.  Secondly, modify the
address portion of the entry names to reflect the difference from the
range modification.
