Talos EVK SMARC support Date: Tue, 31 Mar 2026 11:31:04 +0530 Message-Id: <20260331060107.501561-1-tessolveupstream@gmail.com> X-Mailer: git-send-email 2.34.1 Precedence: bulk X-Mailing-List: devicetree@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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: USB0(usb_1) 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 v16: - Reordered device tree nodes. - Added explanatory comments in talos-evk-usb1-peripheral.dtso. - This patch series depends on the below url https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=next-20260330&id=c1e77b13457d20f14c70e623f7c0a6a3cefc1d67 - No functional change in bindings file. Changes in v15: - Simplified LVDS backlight implementation to use gpio-backlight with GPIO115 only. - Removed previously added extra GPIO(GPIO59) and related gpio- backlight driver changes. - Added #address-cells and #size-cells in &i2c1 to fix dtc warnings. - Added missing reg property for bridge@3d to fix dtc warnings. - This patch series depends on the below url https://lore.kernel.org/linux-arm-msm/e025b1b4-8f5c-4fd2-853e-56b89f1f8e79@oss.qualcomm.com/ - Updated commit messages. - No functional change in bindings file. 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.
