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
Changes in v2:
- Fix for dt_binding_check error.
- Modified base commit to the recent RC1.

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.

I see what we are attempting to do here.
Documentation/devicetree/bindings/remoteproc/ti,k3-dsp-rproc.yaml
probably should strip off the board specifics out in the
examples. but, that belongs to a different patch.

The intention of the patch is to keep only the initial support for the
EAIK board. Subsequent patches will be posted as the testing
completes.

Then, lets wait for the url to be available. k.org record will be for
ever, so, lets make sure that we have this information to aid people

before we consider this series.

For the nodes that are present in k.org, we should probably make up our
minds as to what needs to be the configuration. While I understand
incremental patches, please look through the list to make sure low
hanging items are addressed at the earliest. Commit message makes one
feel that there is tons of nodes that are probably functional, but your
response makes me feel, that is probably not the case - it is hard to
distinguish between the two.

OSPI PHY calibration support is not yet final in mainline. Please drop
partition@3fc0000
Also, please drop u-boot,dm-spl here and elsewhere. This is U-Boot
specific property.
