Focus is on two key hardware components: PURWA-IOT-SOM — A compact System-on-Module integrating the SoC, GPIOs, and PMICs. Designed for modularity, it can pair with various carrier boards to support diverse use cases. PURWA-IOT-EVK — A carrier board tailored for IoT scenarios, providing essential peripherals such as UART, on-board PMICs, and USB components. Together, these components form a flexible and scalable platform. Initial functionality is achieved through proper device tree configuration and driver support. The PURWA-IOT-EVK/SOM shares most of its hardware design with HAMOA-IOT-EVK/SOM, differing primarily in the BOM. Consequently, the DTS files are largely similar. Both platforms belong to Qualcomm’s IQ-X family. For more details on the IQ-X series, see: https://www.qualcomm.com/internet-of-things/products/iq-x-series Hardware differences between HAMOA-IOT and PURWA-IOT: - Display — PURWA uses a different number of clocks and frequency compared to HAMOA. - GPU — PURWA integrates a different GPU. - USB0 — PURWA uses a PS8833 retimer, while HAMOA employs an FSUSB42 as the SBU switch. Features added and enabled: - UART - On-board regulators - Regulators on the SOM - PMIC GLINK - USB0 through USB6 and their PHYs - Embedded USB (eUSB) repeaters - USB Type-C mux - PCIe3, PCIe4, PCIe5, PCIe6a - Reserved memory regions - Pinctrl - NVMe - ADSP, CDSP - WLAN, Bluetooth (M.2 interface) - USB DisplayPort and eDP - Graphics - Audio - TPM Signed-off-by: Yijie Yang --- Changes in v2: - Update the GPU firmware path. - Update the description in the cover letter. - Reorder the patches. - Use separate DTS files for Purwa and Hamoa. - Update base commit. - Link to v1: https://lore.kernel.org/all/20251222-purwa-v1-0-14ab9316e5ff@oss.qualcomm.com/ Changes in v3: - Delete unused PMIC and thermal nodes. - Add WiFi node. - Add display backlight node. - Add connectors and VBUS regulators for USB3 and USB6. - Enable PCIe3 and PCIe5; add PCIe ports along with reset and wake-up GPIOs. - Link to v2: https://lore.kernel.org/r/20260109-purwa-v2-0-f39ee10684cb@oss.qualcomm.com Changes in v4: - Enable TPM. - Update the descriptions for video and the USB OF graph. - Link to v3: https://lore.kernel.org/all/20260113-purwa-v3-0-16eefacbdce9@oss.qualcomm.com/ Changes in v5: - Reorder nodes in purwa-iot-evk.dts. - Update base commit. - The DT binding change that fixes the DT warning for pcie3_phy is located at: https://lore.kernel.org/linux-arm-msm/20260119-topic-purwa_phy_shutup_warning-v1-1-997a692b31c6@oss.qualcomm.com/T/#u - Link to v4: https://lore.kernel.org/r/20260116-purwa-v4-0-89b2adae9f09@oss.qualcomm.com --- Yijie Yang (4): dt-bindings: arm: qcom: Document PURWA-IOT-EVK board firmware: qcom: scm: Allow QSEECOM on PURWA-IOT-EVK arm64: dts: qcom: Add PURWA-IOT-SOM platform arm64: dts: qcom: Add base PURWA-IOT-EVK board Documentation/devicetree/bindings/arm/qcom.yaml | 6 + arch/arm64/boot/dts/qcom/Makefile | 1 + arch/arm64/boot/dts/qcom/purwa-iot-evk.dts | 1549 +++++++++++++++++++++++ arch/arm64/boot/dts/qcom/purwa-iot-som.dtsi | 685 ++++++++++ drivers/firmware/qcom/qcom_scm.c | 1 + 5 files changed, 2242 insertions(+) --- base-commit: 6267b2da1b2d04847a1a8f441e138bc4a89435ee change-id: 20251113-purwa-907ec75b4959 Best regards, -- Yijie Yang
