[PATCH V4 0/3] AM68 SK: Add initial support

[PATCH V4 0/3] AM68 SK: Add initial support

[Sinthu Raja]

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

Hi All,
Respinning this series after rebasing to 6.2.rc1.
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 V4:
=============
Repost after rebasing to 6.2 rc1

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

V1: https://lore.kernel.org/linux-arm-kernel/20221018123849.23695-1-sinthu.raja@ti.com/t/#mbe43b02221733bb6eb06b203359e90ec08406afc
V2: https://lore.kernel.org/lkml/20221107123852.8063-1-sinthu.raja@ti.com/

Krzysztof,
Are you asking about this tag?
Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

As I was rebasing I thought of not adding. Do I need to respin the
patch series with V5 again with the tag?

When you are re-posting OR updating the series, it is the patch sender's
responsibility to pick up the acks. If you are explicitly not picking up
reviews and acks, you should state in the diffstat why.

Also see the b4 tricks[1]

Nishanth,
Thanks for the information.

Krzysztof,
Sorry for the errors caused by my oversight. Kindly excuse me. Would
you want me to resend the V3 series with the correct subject?

Please repost with all tags from all people and properly rebased. This
is weird that once you have in patch a tag, in next version it's gone.
it suggest you sent wrong patch, not previous but one older.

Best regards,
Krzysztof

Sinthu,  If I am not mistaken (Krzysztof can correct me), what is meant here
are two things:

a) if no modification to the patch was made and just a repost is being done,
   just indicate that in $subject. Examples: [1]

b) Ensure that there is a changelog. I understand that the
  cover letter[2] has indicated this, but keep in mind that reviewers use
  filters, and cover-letter does'nt fall into their filter. I usually
  capture the change information per patch as well. If you are a b4 fan,
  see Konstantin's tips with B4 in [3][4]

[PATCH V4 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 V4 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.
