[PATCH 0/3] Adding device tree and binding for Nvidia mgx cx8 switchboard

[Marc Olberding <molberding@nvidia.com>]

Patch 1 Adds the binding for the Nvidia mgx cx8 switchboard
Patch 2 Adds dtsi's for the mgx cx8 switchboard itself
Patch 3 Adds the dts for the mgx cx8 switchboard motherboard reference implementation.

This is an Aspeed AST2600 based reference implementation for a BMC
managing an Nvidia mgx cx8 switchboard. Dtsi files are broken out for
managing the mgx cx8 switchboard over i2c, so that others may reuse these
if they choose to implement their own board. There are two dtsi files
since the i2c topology is not symmetric between busses going to the mgx cx8
switchboard.

Reference to Ast2600 SoC [1].
