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.
