[PATCH] ARM: dts: AM571x-IDK Initial Support

[Lokesh Vutla]

From: Schuyler Patton <spatton-l0cyMroinI0@public.gmane.org>

The AM571x-IDK board is a board based on TI's AM5718 SOC
which has a single core 1.5GHz A15 processor. This board is a
development platform for the Industrial market with:
- 1GB of DDR3L
- Dual 1Gbps Ethernet
- HDMI,
- PRU-ICSS
- uSD
- 16GB eMMC
- CAN
- RS-485
- PCIe
- USB3.0
- Video Input Port
- Industrial IO port and expansion connector

The link to the data sheet and TRM can be found here:

http://www.ti.com/product/AM5718

Initial support is only for basic peripherals.
