AM642 StarterKit (SK) board is a low cost, small form factor board
designed for TI’s AM642 SoC. This series introduces basic support for
AM642 SK.
* Depends on Dave's series for adding AM642 SoC:

AM642 StarterKit (SK) board is a low cost, small form factor board
designed for TI’s AM642 SoC. It supports the following interfaces:
* 2 GB LPDDR4 RAM
* x2 Gigabit Ethernet interfaces capable of working in switch and MAC mode
* x1 USB 3.0 Type-A port
* x1 UHS-1 capable µSD card slot
* 2.4/5 GHz WLAN + Bluetooth 4.2 through WL1837
* 512 Mbit OSPI flash
* x2 UART through UART-USB bridge
* XDS110 for onboard JTAG debug using USB
* Temperature sensors, user push buttons and LEDs
* 40-pin Raspberry Pi compatible GPIO header
* 24-pin header for peripherals in MCU island (I2C, UART, SPI, IO)
* 54-pin header for Programmable Realtime Unit (PRU) IO pins
* Interface for remote automation. Includes:
* power measurement and reset control
* boot mode change
Add basic support for AM642 SK.

Hi Lokesh Vutla,
I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[1/2] dt-bindings: arm: ti: Add bindings for AM642 SK
commit: 905627a3e9f48a094c7e28beba19b687e2e33d98
[2/2] arm64: dts: ti: Add support for AM642 SK
commit: 40b329e4df7a140d678cb3ce47158267f6625d43
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
