Talos EVK SMARC support Date: Tue, 30 Dec 2025 18:32:22 +0530 Message-Id: <20251230130227.3503590-1-tessolveupstream@gmail.com> X-Mailer: git-send-email 2.34.1 Precedence: bulk X-Mailing-List: linux-arm-msm@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Type: text/plain; charset=yes 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 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 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.
