Add Qualcomm Technologies, Inc. Talos EVK SMARC support

The USB PHY nodes has inconsistent labels as 'usb_1_hspy' and 'usb_hsphy_2' across talos.dtsi and qcs615-ride.dts. This patch renames them to follow a consistent naming scheme.

Sorry for only noticing this now, but usb_hsphy_x is wrong..

*every* other dtsi uses usb_x_hsphy, please flip it around

$ rg 'usb_1_hsphy' arch -l | wc -l
93

$ rg 'usb_hsphy_1' arch -l |  wc -l
0

The USB PHY nodes has inconsistent labels as 'usb_1_hspy' and 'usb_hsphy_2' across talos.dtsi and qcs615-ride.dts. This patch renames them to follow a consistent naming scheme.

Could you please confirm if this change aligns with your expectation.

Add the device tree for the QCS615-based Talos EVK platform. The platform is composed of a System-on-Module following the SMARC standard, and a Carrier Board.

The Carrier Board supports several display configurations, HDMI and LVDS. Both configurations use the same base hardware, with the display selection controlled by a DIP switch.

Use a DTBO file, talos-evk-lvds-auo,g133han01.dtso, which defines an overlay that disables HDMI and adds LVDS. The DTs file talos-evk can describe the HDMI display configurations.

The initial device tree includes support for:
- CPU and memory
- UART
- GPIOs
- Regulators
- PMIC
- Early console
- AT24MAC602 EEPROM
- MCP2515 SPI to CAN
- ADV7535 DSI-to-HDMI bridge
- DisplayPort interface
- SN65DSI84ZXHR DSI-to-LVDS bridge
- Wi-Fi/BT

Both usb devices have been configured to host mode, do we need adb? The adb only work with usb peripheral mode.

Thanks,

Add the device tree for the QCS615-based Talos EVK platform. The platform is composed of a System-on-Module following the SMARC standard, and a Carrier Board.

The Carrier Board supports several display configurations, HDMI and LVDS. Both configurations use the same base hardware, with the display selection controlled by a DIP switch.

Use a DTBO file, talos-evk-lvds-auo,g133han01.dtso, which defines an overlay that disables HDMI and adds LVDS. The DTs file talos-evk can describe the HDMI display configurations.

The initial device tree includes support for:
- CPU and memory
- UART
- GPIOs
- Regulators
- PMIC
- Early console
- AT24MAC602 EEPROM
- MCP2515 SPI to CAN
- ADV7535 DSI-to-HDMI bridge
- DisplayPort interface
- SN65DSI84ZXHR DSI-to-LVDS bridge

Neither of these links is relevant to the question.

In our hardware design, the USB0 controller is a USB 3.0-capable controller whose high‑speed (HS) differential lines are routed through a mechanical switch.

a) During EDL (flashing) mode:
The HS lines are explicitly routed to the Micro‑USB port. This allows the SoC to enter "device mode" for firmware flashing.

b) After EDL completes (normal operation):
The mechanical switch is driven to route the HS signals to the on‑ board USB 3.0 hub.
The hub connects to four Type-A ports, all designed for host mode only.
The Micro-USB connector is now electrically disconnected.

Why host-only mode: Once the switch routes to the hub, there's no electrical path back to the Micro-USB port. The USB controller can only talk to the hub and its downstream Type-A ports, which are wired for host mode only. Device mode is physically impossible in this configuration.
Therefore, USB0 must be configured as host-only in the device tree, since device mode cannot work after the system boots.

The USB1 controller supports USB 2.0 and has its data lines directly routed to a Type-A connector. This hardware design restricts the controller to host-only operation, preventing any peripheral/device mode functionality.

Please add a comment regarding EDL-mode DIP switch and describe the onboard HUB in the DT. Additionally consider adding the USB-peripheral overlay, corresponding to the EDL-mode configuration as some labs will not trigger the DIP switch at runtime and settle with the peripheral-only setting for the USB controller.

2.34.1

Add the device tree for the QCS615-based Talos EVK platform. The platform is composed of a System-on-Module following the SMARC standard, and a Carrier Board.

The Carrier Board supports several display configurations, HDMI and LVDS. Both configurations use the same base hardware, with the display selection controlled by a DIP switch.

Use a DTBO file, talos-evk-lvds-auo,g133han01.dtso, which defines an overlay that disables HDMI and adds LVDS. The DTs file talos-evk can describe the HDMI display configurations.

The initial device tree includes support for:
- CPU and memory
- UART
- GPIOs
- Regulators
- PMIC
- Early console
- AT24MAC602 EEPROM
- MCP2515 SPI to CAN
- ADV7535 DSI-to-HDMI bridge
- DisplayPort interface
- SN65DSI84ZXHR DSI-to-LVDS bridge
- Wi-Fi/BT

The output-low/high properties should be unnecessary since the drivers that requests the connected GPIOs control their state

otherwise, I think it's time to finally close in on this..
