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 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,
Sudarshan

The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.

Okay, got it. Will check and update the dependency in the next patch.

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
