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

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

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

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)

On the blackrock platform, for this controller, are there all 4 ports 
given out for use or only one ?

Because if all 4 are there, you might need to give all 4 pinctrls (one 
for each TS3USB221A mux select) here for usb_2 node. If only one port is 
given out for use on the platform, then only one phy (of the 4 activated 
below) needs to be marked as active.

In my case, in [1] on the ADP platform, I marked them as always on for 
all gpios on multiport controller since driver had no support added yet.

Hi Krishna,

thank you for the hints. Unfortunately, I don't have any schematics for
the box. But I tested out activation combinations for all the
usb_2_hsphy and usb_2_qmpphy listed. All of these are also listed in the
usb_2 node in sc8280xp.dtsi. And they all need to be activated to get
the whole usb_2 node up. Leaving out one lets the whole node vanish.
Maybe it is possible to define fewer phys in the usb_2_dwc3 node, I
don't know. The definition as it is now appears to be a safe bet.
What I noticed in the tests was that the pinctrl usb2_en_state had no
effect here. Although, it apparently was required when it was introduced
[1] by Merck Hung and xlazom00@gmail.com. Therefore I am hesitant to
remove it. Also, there may be a hint that it is the enable pin of a hub:

$lsusb -tv
[...]
/:  Bus 005.Port 001: Dev 001, Class=root_hub, Driver=xhci-hcd/4p, 480M
     ID 1d6b:0002 Linux Foundation 2.0 root hub
     |__ Port 001: Dev 002, If 0, Class=Hub, Driver=hub/4p, 480M
         ID 045e:0c5f Microsoft Corp.
/:  Bus 006.Port 001: Dev 001, Class=root_hub, Driver=xhci-hcd/2p, 10000M
     ID 1d6b:0003 Linux Foundation 3.0 root hub
     |__ Port 001: Dev 002, If 0, Class=Hub, Driver=hub/4p, 10000M

Driver=r8152, 5000M
             ID 045e:0c5e Microsoft Corp.

For the IDs 045e:0c5e..045e:c60 there isnot much info, only that its
usually a 10/100/1000 r8152 ethernet adapter, and a USB3.2 /USB2.1 4
port hub. How this is wired, though, no idea. In the face of this I
would suggest to keep the definition as it is now.

My point is little different.
Third controller supports upto 4 physical ports. How many of them have 
been exposed on this WDK2023 ? Depending on that, the phys have to be 
enabled in DT.

Okay I took the jump and reduced usb_2_dwc3 to only one qmpphy and one
hsphy. It works, the USB nodes look the same and work. What an odd
design, though, but why not.

&usb_2_dwc3 {
     phys = <&usb_2_hsphy0>, <&usb_2_qmpphy0>;
     phy-names = "usb2-0", "usb3-0";
};

I will do an amended V8 of the patch. Thank you for the hint again.

with best regards

Jens

Also, if there is only one port, then don't enable the other PHYs.
