The AM572x-IDK board is a board based on TI's AM5728 SOC which has a dual core 1.5GHz A15 processor. This board is a development platform for the Industrial market with: - 2GB 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/AM5728 This patch creates a common dtsi file that will provide a common board dtsi file to define the nodes that are common to AM57xx (including the upcoming AM5718) IDK boards. Initial support is only for basic peripherals Signed-off-by: Schuyler Patton <spatton@ti.com> Signed-off-by: Nishanth Menon <nm@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
