[PATCH v6 0/3] arm64: dts: qcom: sc8280xp-blackrock: dt definition for Windows Dev Kit 2023

[Jens Glathe via B4 Relay]

"Microsoft Windows Dev Kit 2023" aka "Blackrock" aka "Project Volterra"

Device tree for the Microsoft Windows Dev Kit 2023. This work
is based on the initial work of Merck Hung <merckhung@gmail.com>.

The Windows Dev Kit 2023 is a nice little desktop based on sc8280xp.
Link: https://learn.microsoft.com/en-us/windows/arm/dev-kit/

Supported features:
- USB type-c and type-a ports
- minidp connector
- built-in r8152 Ethernet adapter
- PCIe devices
- nvme
- ath11k WiFi (WCN6855)
- WCN6855 Bluetooth
- A690 GPU
- ADSP and CDSP
- GPIO keys
- Audio definition (works via USB)

Original work: https://github.com/merckhung/linux_ms_dev_kit/blob/ms-dev-kit-2023-v6.3.0/arch/arm64/boot/dts/qcom/sc8280xp-microsoft-dev-kit-2023.dts

This dt is more or less deducted from the Thinkpad X13s.
It contains a lot of guesswork, and also a lot of research on
what works with the Windows Dev Kit.

The WiFi definition references qcom,ath11k-calibration-variant = "MS_Volterra"
which is unfortunately not yet in the linux-firmware. The ath11k driver finds
the default one for 
"bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2|18,qmi-board-id=255"
when the entry with the variant is not found which is quite sub-optimal. I 
have placed a pr on github/qca-swiss-army-knife:
https://github.com/qca/qca-swiss-army-knife/pull/9 that provides an amended 
board-2.bin and a board-2.json to generate it. 

pcie2 (nvme) is intentionally specified as max-link-speed = <4>. The 
interface is capable of it, most current nvme ssds are capable of it, 
but the physical slot isn't. This leads to a silent downgrade to <3> instead 
of the "device is limited by bus, capable of..." message.

It is in use and under development since May 2023, pretty stable now.

Changes in v6:
- added missing acked-by tag from Krzysztof
- removed aspm-no-l0s from the PCIe ports as suggested by Johan
- corrected max-link-speed to <4> on PCIe2 as suggested by Johan
- changed WLAN variant description to "MS_Volterra", added Kalle Valo 
  for approval / guidance
- trimmed the supply statements on hsphy and other pcie ports for what 
  is known and defined on the Thinkpad X13s
- Link to v5: https://lore.kernel.org/r/20241030-jg-blackrock-for-upstream-v5-0-830c938437ad@oldschoolsolutions.biz

Changes in v5:
- removed s-o-b from Merck Hung as suggested by Bjorn Andersson. The credits
  for the original work are in the cover letter and in the dts commit
- removed Venus codec from the list of supported features. It is, but that
  part is not in this patch set.
- Link to v4: https://lore.kernel.org/r/20241027-jg-blackrock-for-upstream-v4-0-703b254fc95f@oldschoolsolutions.biz

Changes in v4:
- removed the redundant regulator definitions
- changed the pinctrl property order
- use microsoft instead of MICROSOFT as subdirectory and device name component
- amend spacing in audio nodes
- change external connector dp1 for mini-dp to DP-3 for consistency
- Link to v3: https://lore.kernel.org/r/20241013-jg-blackrock-for-upstream-v3-0-839d3483a8e7@oldschoolsolutions.biz

Changes in v3:
- tried to heed all advice and comments given - thank you
- re-ordered patches to definition before use
- added "microsoft,blackrock" as compatible in QSEECOM driver
- removed the qseecom node
- ordered nodes alphabetically {address, node name, label}
- amended indentation
- consistently used blackrock as identifier / directory name
- sorted identifiers by the same order for multiple instances
- added some explanation re WiFi
- added definition for PMU on the WCN6855
- added some explanation for pcie2 max-link-speed
- Link to v2: https://lore.kernel.org/r/20240920-jg-blackrock-for-upstream-v2-0-9bf2f1b2191c@oldschoolsolutions.biz

Changes in v2:
- removed whitespaces and breaks
- added compatibility binding
- added feature list
- reformatted Signed-off list
- Link to v1: https://lore.kernel.org/r/5f5487e1-e458-4a3a-af02-c52e50ca1964@oldschoolsolutions.biz

[PATCH v6 1/3] dt-bindings: arm: qcom: Add Microsoft Windows Dev Kit 2023

[Jens Glathe via B4 Relay]

From: Jens Glathe <jens.glathe@oldschoolsolutions.biz>

Add compatible values for the Microsoft Windows Dev Kit (WDK2023)
with its codename "blackrock". The Dev kit is a small desktop box
based on the mainboard of the Surface pro 9 5G, intended for
developers to test/build arm64-based Windows software.

qca-swiss-army-knife is only for scripts or similar, not for board
files. For ath11k board files it's best to file a bug in bugzilla:

https://wireless.docs.kernel.org/en/latest/en/users/drivers/ath11k/bugreport.html

For ath11k discussions we have a mailing list, adding it now:

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

 From what I remember, the phy names for multiport must be "usb2-X"  or 
"usb3-X". The above notation might compile but If I am not wrong, the 
phys won't be active. How was USB tested in this case ?

Moreover just marking status as "okay" for usb_2 must work like done in 
[1] and [2] and there is no need for explicitly marking dr_mode as host 
again and refactoring the phy-names.

[2]: 
https://patchwork.kernel.org/project/linux-arm-msm/patch/20240501065641.965-1-johan+linaro@kernel.org/

Please fix this up.

Krishna,

All 4 type-a ports are working at full capacity, I assume the phys are
up. On one of these is the internal r8152 adapter. Actually when I
started with the WDK the type-a ports were the most reliable ones. The
box is my daily driver, so its extensively tested for ~18 months now.

Please update this atop

<20241018-sc8280xp-pwrseq-v6-0-8da8310d9564@linaro.org>

most notably including a new supply (which will likely be identical)

Please don't break the line, see e.g. x1e80100-crd.dts

Oh, this thing has a speaker!

Sorting GPIOs by their number is preferred

Do we know what these are for? If so, please describe it (also
like in x1e80100-crd.dts)

Well, no. Will take another look at it. Interestingly, the SnapDragon
Dev Kit (x1e) has a panel for speakers. So, maybe they are there on an
unused panel.
