ARM: dts: add support for AM437x IDK
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).
