Subject[PATCH v3 16/20] ARM: dts: aspeed: Add Ingrasys Zaius BMC machine
Date
From: Xo Wang <xow@google.com>

Zaius is a POWER9 platform announced at OpenPOWER Summit 2016. This adds
basic DTS support for its AST2500 BMC.

This adds the device tree description for most upstream components. It
is a squashed commit of all of the patches from the OpenBMC kernel tree.
