[PATCH 0/9] MIPS: Add support for more mscc SoCs: Luton, Serval and Jaguar2

[Gregory CLEMENT]

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.

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.

Gregory

[PATCH 3/9] MIPS: mscc: Prepare configuration to handle more SoCs

[Gregory CLEMENT]

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.

[PATCH 4/9] MIPS: mscc: Fix configuration name for ocelot legacy boards

[Gregory CLEMENT]

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.

[PATCH 9/9] MIPS: mscc: Add serval support

[Gregory CLEMENT]

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>.

Re: [PATCH 1/9] dt-bindings: mips: Add luton

[Gregory CLEMENT]

Hello

This patch is a leftover, the correct one is the other one. Actually the
only difference is using "Luton" instead of "luton" in the topic.

The i2c device node name are wrongs, I missed it for this submission and
will fix it in the next version.

For instance i2c_x2sfp_1_a@0 will be named i2c@0.
