K2G SoC family is the newest version of the Keystone family of processors.
The technical reference manual for K2G can be found here:
http://www.ti.com/lit/ug/spruhy8/spruhy8.pdf
Add new bindings for K2G and the K2G evm. Also document these new bindings.

K2G is the newest addition of TI's Keystone 2 product family. It is a
single core Cortex A15 and a C66x DSP.
K2G supports standard peripherals such as SPI, UART, MMC and USB 2.0.
Includes two dual-core Programmable Real-time Unit and Industrial
Communication Subsystems (PRU-ICSS).
The technical reference manual for K2G can be found here:
http://www.ti.com/lit/ug/spruhy8/spruhy8.pdf
This device is targeted for a variety of applications which include, but
are not limited to:
Home audio
Professional audio
Industrial Programmable Logic Control
The peripheral nodes that have been included in this patch have been
tested during bring-up. Since all peripherals will not necessarily be
used on all boards, disable all peripherals by default. This allow
the board dts to selectively choose which peripherals it wants to
enable.
This SoC now uses the next generation of power management architecture
with the PM functionality located in a microcontroller embedded in the SOC.
Support for this new PM architecture along with other peripherals will be
added in future patches.

Add barebones K2G evm dts. This DTS allows the board to boot using a
ram based filesystem.

Quick scan of the series looks fine to me. I will wait for others to
come back for a week or so and then add to 4.6 queue.
Thanks for the series !!
