The HAMOA-IOT-EVK is an evaluation platform for IoT products, composed of
the Hamoa IoT SoM and a carrier board. Together, they form a complete
embedded system capable of booting to UART.
This change enables and overlays the following peripherals on the carrier
board:
- UART
- On-board regulators
- USB Type-C mux
- Pinctrl
- Embedded USB (EUSB) repeaters
- NVMe
- pmic-glink
- USB DisplayPorts
Written with contributions from Shuai Zhang (added Bluetooth) and Yongxing
Mou (added USB DisplayPorts).

> No retimers on SS0?
Similar to the QCP, the EVK does not use Parade PS8830 retimers on the
SS0. Instead, each port uses an FSUSB42 USB switch to handle orientation
switching for the SBU lines.

> Could you please point out, why?
According to the schematic, there is a regulator and a retimer (PS8830).
However, as mentioned above, the retimer is not connected to USB 0 and
is therefore not used in the EVK. As a result, the regulator is left
unused in this context.

It is used to switch data lines between USB Type-C orientation detection
and DisplayPort AUX channels. When this GPIO is high, USB0 operates in
orientation detection mode.

This pin functions similarly to usb-1-ss0-sbu-state; it controls the
data switch between signals from the USB connector and WLAN data.

I don't think I follow it here. Which data lines? Type-C orientation
detection uses CC1 / CC2, DP AUX use SBU lines.

Could you please explain it? Does it toggle USB2 signals(you've added it
to the USB2 PHY) being routed either to the USB connector or to the WiFi
card? Or do you mean something else?

I made a mistake here — this pin switches between two data sources: one
is DP AUX, and the other is a GPIO pair configured with the function
usb0_sbrx/usb0_sbtx. Both data sources originate from the SoC and are
routed to the USB0_SBU1 and USB0_SBU2 lines of the USB Type-C connector.

This means the switch will select the GPIO pair configured as
usb0_sbrx/usb0_sbtx.

Yes, that's right. It routes signals between the USB connector and the
M.2 Wi-Fi card.

Ok. please add a comment. If the retimer is connected to I2C bus, please
define it too.

So, it's some USB4 stuff. Ideally it should be described via the
gpio-sbu-mux, but I don't think we can do that for now. I'd let Bjorn,
Konrad or Abel comment on this.

It’s not connected to I2C. I will add a comment here.

Are you sure? Turning off Wi-Fi sounds like a valid usecase..

Hi Konard, It is m.2 interface on Hamoa. The PCIe power of m.2 should be always on.
Even on QCOM's B2B interface, we are unable to dynamically control the power of PCIe devices on upstream kernel.
The PCIe specification does not support dynamic power control between the PCIe device and the RC.
PCIe power should be always on here.
