[PATCH 0/2] H100 support

[Lucas Stach]

This adds support for the H100 baseboard. Series is on top of -next
as the base DT for this board is only in Linux 4.8.

[PATCH 2/2] ARM: imx6: add support for Auvidea H100

[Lucas Stach]

The Auvidea H100 is a baseboard for the SolidRun MicroSOM, which
provides HDMI IN/OUT capabilities.

Currently supported is only a combination of the H100 baseboard
with a i2eX MicroSOM.
