On these boards NAND ready pin status is avilable over
GPMC_WAIT0 pin.

For NAND we don't use GPMC wait pin monitoring but
get the NAND Ready/Busy# status using GPIOlib.
GPMC driver provides the WAIT0 pin status over GPIOlib.

Read speed increases from 16516 KiB/ to 18813 KiB/s

- 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

TI's Industrial Communication Engine EVM is a low cost hardware mainly
developed for industrial communication type applications using serial
or Ethernet based interfaces. This platform features TI's AM3359 with
800MHz single core Cortex-A8 processor, 256MB DDR3, 64MB SPI flash,
8MB NOR Flash, mmc, usb, can, dual Ethernet ports.

For more information, look at HW user guide[1], Data manual[2].

Just add basic support for the moment.

The binding definition for the PCF857x GPIO expanders doesn't mention
a "ti,pcf8575" compatible string.  This is apparently because TI is
only a second source - there is no functional difference between
PCF8575 chips manufactured by TI and NXP, and the same board might be
populated with either depending on availability.

This is not a problem in practice because the I2C core uses
of_modalias_node() before matching drivers and this strips the
manufacturer name.

McASP3 does not support constant addressing mode on the DAT
port, so increment transfers must be used instead.  This
restriction is also applicable for McASP1 and McASP2.

This DMA addressing constraint poses a major problem for sDMA
where constant addressing mode is used on the peripheral side.
Unfortunately, using increment transfers in sDMA comes with
important side effects.

The addressing mode used in eDMA is INC, so the silicon limitation
described above has no impact and the McASP3 DAT port can be
safely added by switching to eDMA instead of sDMA.
