ARM: dts: add support for AM437x IDK
Browse files Browse the repository at this point in the history 
The AM437x Industrial Development Kit (IDK) is
an application development platform targeted at
industrial communication and control applications.

It comes with a 3-phase motor driver, PROFINET,
PROFIBUS and a few other industrial communication
interfaces.

The board has 1GiB of DDR3 RAM, QSPI NOR flash,
a 100% discrete power design (no PMIC) and an
on-board 2MP camera (not supported with Linux
as of this writing).
