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 next patches 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 and switching cannot be handled from SW.
USB0 is configured host-only in the base device tree, hence host-only
mode is supported on Linux boot up.
For ADB to work during normal runtime, a separate device-tree overlay
enables the Micro-USB peripheral configuration.
Changes in v14:
- Added DT aliases for i2c1, i2c5, and spi6.
- Dropped unrelated talos.dtsi and qcs615-ride.dtsi modifications
(handled in separate patches).
- Updated commit messages.
- Updated USB note in the cover letter for maintainers' awareness.
- Ignore v13 patch.
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). (suggested by Konrad)
- 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. (suggested by Dmitry)
- 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

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.

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.
Add talos-evk-usb1-peripheral.dtso overlay to enable USB0 peripheral
(EDL) mode. The base DTS will keep USB0 host-only due to hardware
routing through the EDL DIP switch, and the overlay switches the
configuration for device-mode operation.
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 controller’s HS differential pair is switched (manually)
+ * between the Micro-USB port for EDL/ADB and the on-board USB 3.0 hub.
+ *
+ * During EDL (Emergency Download) mode, the HS lines are explicitly
+ * routed to the Micro-USB port to allow the SoC to enter device mode
+ * for flashing.
+ *
+ * After EDL the switch is normally toggled so the HS lines stay
+ * connected to the hub’s Type-A downstream ports, leaving no electrical
+ * path to the Micro-USB connector — therefore USB0 runs host-only in
+ * normal runtime and device mode must not be advertised.
+ *
+ * USB0 is configured host-only in the base device tree; a separate
+ * device-tree overlay enables the Micro-USB peripheral configuration for
+ * ADB. For ADB to work during normal runtime the DIP switch SW1 must be
+ * manually toggled to the off position (reconnecting the HS pair to the
+ * Micro-USB port).

Thank you for pointing this out and for sharing the build warnings.
I will review the reported DT issues, verify the root causes, and address
them accordingly. The fixes will be included in the next revision of the
patch series.

I rechecked this 'psci: 'reboot-mode' does not match any of the regexes'
issue on my side using linux-next tag 'next-20260223', but I
was not able to reproduce the reported error.
Could you please share the exact tree/commit and configuration you used
for the build? I would like to align my environment and investigate this
further.

The missing clock-names property issue is already being addressed by the
following patch:
https://lore.kernel.org/linux-arm-msm/e025b1b4-8f5c-4fd2-853e-56b89f1f8e79@oss.qualcomm.com/
I will reference this dependency in the next revision of my patch series
(commit notes)to ensure the build and schema checks are aligned.

I rechecked the 'Unevaluated properties are not allowed ('cooling' was unexpected)'
issue locally using linux-next tag 'next-20260223', but I was not able to reproduce
this issue.
Additionally, I am not introducing or modifying any cooling-related nodes
in my DTS/DT overlay.The cooling property appears to originate from the base
talos.dtsi, and is not touched or referenced by my patch series.
