[PATCH V5 0/3] AM68 SK: Add initial support

[PATCH V5 0/3] AM68 SK: Add initial support

[Sinthu Raja]

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

Hi All,
This series of patches add support for AM68 Starter kit(SK). AM68 SK
is a low cost, small form factor board designed for TI’s AM68 SoC.

Refer below link to AM68 Technical Reference Manual for further details: 
http://www.ti.com/lit/pdf/spruj28

Design files can be referrred from https://www.ti.com/lit/zip/SPRR463

Changes in V5:
=============
Address review comments:
- Remove the unessential comment.
- Remove alignment property from secure-ddr node, as no memory is allocated out
  of this region.

Changes in V4:
=============
Repost after rebasing to 6.2 rc1

Changes in  V3:
==============
Address all the review comments and the changes are captured in separate patches.
 - Remove the unused nodes that are disabled by default.
 - Update the gpio regulator node: gpio-regulator-tlv to "regulator-tlv".

[PATCH V5 2/3] arm64: dts: ti: Add initial support for AM68 SK System on Module

[Sinthu Raja]

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

AM68 Starter Kit (SK) is a low cost, small form factor board designed
for TI’s AM68 SoC. TI’s AM68 SoC comprises of dual core A72, high
performance vision accelerators, hardware accelerators, latest C71x
DSP, high bandwidth real-time IPs for capture and display. The SoC is
power optimized to provide best in class performance for industrial
applications.

    AM68 SK supports the following interfaces:
      * 16 GB LPDDR4 RAM
      * x1 Gigabit Ethernet interface
      * x1 USB 3.1 Type-C port
      * x2 USB 3.1 Type-A ports
      * x1 PCIe M.2 M Key
      * 512 Mbit OSPI flash
      * x2 CSI2 Camera interface (RPi and TI Camera connector)
      * 40-pin Raspberry Pi GPIO header

SK's System on Module (SoM) contains the SoC and DDR.
Therefore, add DT node for the SOC and DDR on the SoM.

[PATCH V5 3/3] arm64: dts: ti: k3-am68-sk: Add support for AM68 SK base board

[Sinthu Raja]

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

The SK architecture comprises of baseboard and a SOM board. The
AM68 Starter Kit's baseboard contains most of the actual connectors,
power supply etc. The System on Module (SoM) is plugged on to the base
board. Therefore, add support for peripherals brought out in the base
board.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!

[1/3] dt-bindings: arm: ti: Add binding for AM68 SK
      commit: 73b1c4f5f53e531f75d4b65dec4784cf67e685f2
[2/3] arm64: dts: ti: Add initial support for AM68 SK System on Module
      commit: 2b6277b76d42cbb781c558ea982e23cd770dd363
[3/3] arm64: dts: ti: k3-am68-sk: Add support for AM68 SK base board
      commit: a266c180b398eab5030bdcf2d1bbdc62fb7fc9c1

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.
