Add Qualcomm Technologies, Inc. Talos EVK SMARC support

Hi all,

This patch series adds device tree binding and board support for the Qualcomm Technologies, Inc. Talos EVK SMARC platform based on the QCS615 SoC.

The first patch introduces the DT binding entry for the Talos EVK SMARC board, and the second patch adds the corresponding DTS files for the platform.

Note:
USB(usb_1_dwc3) supports host-only mode based on the switch SW1 on the SoM, which is purely a hardware controlled as USB-ID and USB-VBUS is not connected the switching cannot be handled from SW. Hence from SW Host-only mode is supported on Linux boot up.

Changes in v13:
- The USB HS PHY node naming has been corrected to follow the existing convention used across the tree (usb_x_hsphy instead of usb_hsphy_x).
- Removed unnecessary output-low from the wlan_en_state node.
- Updated WiFi DT to control PA power through WLAN_EN, removing separate regulator definitions.
- Added USB peripheral overlay allowing USB0 to operate in device mode when required.
- Updated commit messages.
- No functional change in bindings file.

Changes in v12:
- qcs615-ride.dts patch squashed with talos.dtsi patch. (suggested by Konrad)
- Added static power supply node for lvds-panel.
- The ti,dsi-lanes, ti,lvds-format, and ti,lvds-bpp properties dropped because they were redundant for the current panel/bridge configuration.
- No functional change in bindings file.

Changes in v11:
- Fixed inconsistent USB PHY node naming in qcs615-ride.dts to align with the expected naming convention. (suggested by yuanjiey)
- Reordered properties in property-n and property-names for consistency across DT files.
- Removed unnecessary output-low from the bt_en_state node.
- Used a &label_reference for hdmi_connector.
- Added pcieport0 device node, which is required for WLAN to power on.
- No functional change in bindings file.

Changes in v10:
- This series extends the gpio-backlight driver and its DT bindings to support multiple control GPIOs. (suggested by Dmitry)
- Addressed DT node labeling feedback.
- Polished overall device tree structure and minor formattings.
- Corrected pinctrl configuration for the active-low PERST# pin.
- Includes a fix for inconsistent USB PHY node naming in talos.dtsi. (suggested by Dmitry)
- Enabled WiFi and Bluetooth functionality.
- Updated commit message.
- No functional change in bindings file.

Changes in v9:
- The updates in the following patch url is taken care in this patch series.
https://lists.freedesktop.org/archives/dri-devel/2025-November/534473.html
- Ignore v8 patch

Changes in v8:
- This patch series depends on the below url
https://lists.freedesktop.org/archives/dri-devel/2025-November/534473.html
- Moved the contents of talos-evk-cb.dtsi to talos-evk.dtsi which will describe all the standard configuration of the EVK.
- Introduced 'talos-evk-lvds-auo,g133han01.dtso' which has overlay to disable HDMI and adds the LVDS-related on top of the base dts file. (suggested by Bjorn)
- Ethernet and Wi-Fi/BT are not (yet) supported.
- Updated commit message.
- No functional change in bindings file.

Changes in v7:
- Added i2c clock frequency for i2c5 node.
- Moved adv7535 controller section to talos-evk.dts file.
- Reorder the usb nodes.
- GPI_DMA nodes added in the device tree files.
- No functional change in bindings file.

Changes in v6:
- Clarified description of talos-evk-cb.dtsi to explain that it defines common carrier board interfaces shared between HDMI and LVDS variants, And It’s a single carrier board. HDMI and LVDS share the same DSI interface, and only one can be active at a time depending on a DIP switch.
- Added missing newlines before 'status' and between the last property and subnode (suggested by Konrad).
- Updated commit messages for clarity.

Changes in v5:
- Updated commit message. (suggested by Krzysztof)
- Introduced generic node name for can, dp, hdmi-bridge. (suggested by Krzysztof)
- Introduced talos-evk-cb.dtsi, which has common carrier board interfaces.
- No functional change in bindings file.

Changes in v4:
- Updated product name to full form per Krzysztof’s feedback in dt-binding comment.
- Hook up the ADV7535 DSI-to-HDMI bridge to base DTS file.
- Add DP connector node and MDSS DisplayPort controller.
- Added USB note in the cover letter for maintainers' awareness.

Changes in v3:
- Addressed comments from Dmitry regarding USB1 dr_mode and added a DTS comment.
- No functional change in bindings file.

Changes in v2:
- Renamed compatible to "qcom,talos-evk" (suggested by Dmitry/Bjorn)
- Merged enum entry with existing qcs615-ride block (Krzysztof)
- Fixed subject and commit message to use imperative mood.

Thanks,
Anusha

2.34.1

The USB PHY nodes has inconsistent labels as 'usb_1_hsphy' and 'usb_hsphy_2' across talos.dtsi and qcs615-ride.dts. This patch renames them to follow a consistent naming scheme.

No functional changes, only label renaming.

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.

According to the hardware design and vendor guidance, the WiFi PA supplies VDD_PA_A and VDD_PA_B only need to be enabled at the same time as asserting WLAN_EN.

On this platform, WiFi enablement is controlled via the WLAN_EN GPIO (GPIO84), which also drives the VDD_PA_A and VDD_PA_B power enables. Remove the VDD_PA_A and VDD_PA_B regulator nodes from the device tree and rely on WLAN_EN to enable WiFi functionality.

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

2.34.1

Apologies for the oversight. That change was mistakenly split from the previous patch during preparation of the series.
Thank you for pointing it out. I have corrected the patch set accordingly and will resend the updated version shortly.
