J721E EdgeAI Kit (EAIK) is a low cost, small form factor board designed
for TI’s J721E SoC. This series intoduces the basic support for J721E
EAIK.

From: Sinthu Raja <sinthu.raja@ti.com>

J721E EdgeAI Kit (EAIK) is a low cost, small form factor board designed
for TI’s J721E SoC. TI’s J721E SoC comprises of dual core A72, high
performance vision accelerators, video codec accelerators, latest C71x
and C66x DSP, high bandwidth real-time IPs for capture and display, GPU,
dedicated safety island and security accelerators. The SoC is power
optimized to provide best in class performance for perception, sensor
fusion, localization, path planning tasks in robotics, industrial and
automotive applications.

J721E EAIK supports the following interfaces:
* 4 GB LPDDR4 RAM
* x1 Gigabit Ethernet interface
* x1 USB 3.0 Type-C port
* x3 USB 3.0 Type-A ports
* x1 UHS-1 capable µSD card slot
* x1 PCIe M.2 E Key with x1 USB2.0, x1 MCASP, x1 MMC, x1 UART
* x1 PCIe M.2 M Key
* 512 Mbit OSPI flash
* x4 UART through UART-USB bridge
* x4 CAN-FD interface
* x1 DP interface
* x1 HDMI interface
* x2 CSI2 Camera interface (RPi and TI Camera connector)
* 40-pin Raspberry Pi compatible GPIO header
* Compact TI 20-Pin connector for JTAG debug
* Interface for remote automation. Includes:
   * power measurement and reset control
   * boot mode change

Add basic support for J721E-EAIK.

From: Sinthu Raja <sinthu.raja@ti.com>

J721E EdgeAI Kit (EAIK) is a low cost, small form factor board designed
for TI’s J721E SoC. TI’s J721E SoC comprises of dual core A72, high
performance vision accelerators, video codec accelerators, latest C71x
and C66x DSP, high bandwidth real-time IPs for capture and display, GPU,
dedicated safety island and security accelerators. The SoC is power
optimized to provide best in class performance for perception, sensor
fusion, localization, path planning tasks in robotics, industrial and
automotive applications.

J721E EAIK supports the following interfaces:
* 4 GB LPDDR4 RAM
* x1 Gigabit Ethernet interface
* x1 USB 3.0 Type-C port
* x3 USB 3.0 Type-A ports
* x1 UHS-1 capable µSD card slot
* x1 PCIe M.2 E Key with x1 USB2.0, x1 MCASP, x1 MMC, x1 UART
* x1 PCIe M.2 M Key
* 512 Mbit OSPI flash
* x4 UART through UART-USB bridge
* x4 CAN-FD interface
* x1 DP interface
* x1 HDMI interface
* x2 CSI2 Camera interface (RPi and TI Camera connector)
* 40-pin Raspberry Pi compatible GPIO header
* Compact TI 20-Pin connector for JTAG debug
* Interface for remote automation. Includes:
   * power measurement and reset control
   * boot mode change

Add basic support for J721E-EAIK.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

See https://patchwork.ozlabs.org/patch/1486849

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.

Hi Rob,
Thanks for your comment and valuable inputs. Earlier with the 'make
dt_binding_check', I didn't get the mentioned error. After installing
the yamllint and dt-schema update I am able to see the error(s).
Will fix and resubmit the patches.
