Hello,

Ocelot SoC belongs to a larger family of SoCs called VCoreIII. Luton,
Serval and Jaguar2 are part of this family and are added with this
series.

This the second version with a few changes in device tree.

To be able to run a linux kernel the irqchip support and the pinctrl
support are needed. Two series of patches adding this support has been
posted to their subsystem. However there is no build dependency
between them.

Changelog:
v1 -> v2
 - Moved the changes in binding documentation from patch 8 to 2
 - Fixed i2c devices node name in jaguar2 device tree files
 - Added Acked-by from Rob Herring
 - Fixes few more devices tree nodes, now there is no more warning when
   running "make W=1 dtbs"

Luton SoC belongs to the same family as Ocelot.

Ocelot belongs to a family of SoC named the VCore III. In order to add
these new Soc, use the new symbol SOC_VCOREIII instead of a one
dedicated to Ocelot.

In order to avoid regression on driver building, the MSCC_OCELOT
configuration symbol is kept until the driver will be converted.

Ocelots is supported by the generic MIPS build so make it clears that
LEGACY_BOARD_OCELOT is only needed for legacy boards which didn't have
bootloader supporting device tree.

Add a device trees and FIT image support for the Microsemi Jaguar2 SoC
which belongs to same family of the Ocelot SoC.

It is based on the work of Lars Povlsen <lars.povlsen@microchip.com>.

Add a device trees and FIT image support for the Microsemi Serval SoC
which belongs to same family of the Ocelot SoC.

It is based on the work of Lars Povlsen <lars.povlsen@microchip.com>.
