#1271626 — [PATCH 2/2] ARM: dts: NSP: Add I2C support to the DT

FromJon Mason <jonmason@broadcom.com>

Subject[PATCH 2/2] ARM: dts: NSP: Add I2C support to the DT
Message-ID<qvUA1-Xn-11@gated-at.bofh.it>
In reply to#1271625
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.

#1271628 — [PATCH 1/2] ARM: dts: NSP: Device Tree clean-ups

FromJon Mason <jonmason@broadcom.com>

Message-ID<qvUA1-Xn-15@gated-at.bofh.it>
In reply to#1271625
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.
