[PATCH v13 0/3] Add Qualcomm Technologies, Inc. Talos EVK SMARC support

[Sudarshan Shetty]

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

[PATCH v13 2/3] arm64: dts: qcom: talos/qcs615-ride: Fix inconsistent USB PHY node naming

[Sudarshan Shetty]

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.

[PATCH v13 3/3] arm64: dts: qcom: talos-evk: Add support for QCS615 talos evk board

[Sudarshan Shetty]

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

+ * USB0 routing and EDL mode:

+ * The USB0 high-speed differential pairs are routed via a mechanical
+ * switch controlled by an EDL-mode DIP switch (SW1).
+ *
+ * When the EDL DIP switch is enabled, the HS lines are routed to the
+ * Micro-USB connector, allowing the controller to operate in USB
+ * peripheral (device) mode for firmware flashing.
+ *
+ * In normal operation, the switch routes the HS lines to the onboard
+ * USB 3.0 hub. In this configuration, the Micro-USB connector is
+ * electrically disconnected and the controller can only operate in
+ * host mode.
+ *
+ * Due to this hardware design, USB0 is configured as host-only in the
+ * base device tree. A separate device-tree overlay may be used to
+ * describe the EDL-mode (peripheral-only) configuration.
