…LED variants X1/X1 Plus variant of the said device comes in either FHD+ OLED or FHD+ LCD panel, and shares the same model number UX3407QA. It appears LCD panel's brightness adjustment is PWM backlight controlled, so a dedicated device-tree is required. Introduce dedicated compatibles with fallback to 'asus,zenbook-a14-ux3407qa' as they are otherwise the same.

The laptop comes in two variants: * UX3407RA, higher end, FHD+ OLED or WOXGA+ OLED panels * UX3407QA, lower end, FHD+ OLED or FHD+ LCD panels Even though all three panels work with "edp-panel", unfortunately the brightness adjustmenet of LCD panel is PWM based, requiring a dedicated device-tree. Convert "x1p42100-asus-zenbook-a14.dts" into ".dtsi" to allow for this split, introduce new LCD variant. Leave current variant without postfix and with the unchanged model name, as some distros (eg. Ubuntu) rely on this for automatic device-tree detection during kernel installation/upgrade. As dedicated device-tree is required, update compatibles of OLED variants to correct ones. Keep "edp-panel" as fallback, since it is enough to make the panels work. While at it moving .dts, .dtsi around, drop 'model' from the top level x1-asus-zenbook-a14.dtsi as well.

Unlike the CRD, which shares a single GPIO reset line for WSA1/2, this board provides a dedicated GPIO reset for each WSA, resulting in 4 separate reset lines. Update the device tree accordingly so that all 4 speakers can playback audio as expected.

… for Type-A ports The Multiport controller on Hamoa EVK platform is connected to Two Type-A ports. VBUS for each of these ports are provided by a TPS2559QWDRCTQ1 regulator, controlled from PMIC GPIOs. Add the necessary regulators and GPIO configuration to power these. Implement connector nodes to embed the vbus supply within them. Since there is no entity currently that can read vbus supply from a Type-A connector and control it, mark the supplies as always on.

These interfaces require multiple voltage rails: PCIe5 needs 3.3V supplied by vreg_wwan, while PCIe3 requires 12V, 3.3V, and 3.3V AUX rails, controlled via PMIC GPIOs. Add the required fixed regulators with related pin configuration, and connect them to the PCIe3 and PCIe5 ports to ensure proper power for the SDX65 module and SATA controller.

The PURWA-IOT-SOM is a compact computing module that integrates a System on Chip (SoC) — specifically the x1p42100 — along with essential components optimized for IoT applications. It is designed to be mounted on carrier boards, enabling the development of complete embedded systems. Purwa uses a slightly different Iris HW revision (8.1.2 on Hamoa, 8.1.11 on Purwa). Support will be added later. Make the following peripherals on the SOM enabled: - Regulators on the SOM - Reserved memory regions - PCIe3, PCIe4, PCIe5, PCIe6a - USB0 through USB6 and their PHYs - ADSP, CDSP - Graphic Link: https://lore.kernel.org/all/20260202073555.1345260-3-yijie.yang@oss.qualcomm.com/ Reviewed-by: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com> Signed-off-by: Yijie Yang <yijie.yang@oss.qualcomm.com>
The PURWA-IOT-EVK is an evaluation platform for IoT products, composed of the Purwa IoT SoM and a carrier board. Together, they form a complete embedded system capable of booting to UART. PURWA-IOT-EVK uses the PS8833 as a retimer for USB0, unlike HAMOA-IOT-EVK. Meanwhile, USB0 bypasses the SBU selector FSUSB42. Make the following peripherals on the carrier board enabled: - UART - On-board regulators - USB Type-C mux - Pinctrl - Embedded USB (EUSB) repeaters - NVMe - pmic-glink - USB DisplayPorts - Bluetooth - WLAN - Audio - PCIe ports for PCIe3 through PCIe6a - TPM Link: https://lore.kernel.org/all/20260202073555.1345260-4-yijie.yang@oss.qualcomm.com/ Signed-off-by: Yijie Yang <yijie.yang@oss.qualcomm.com>

…h USB and UART When Bluetooth supports both USB and UART, the BT UART driver is always loaded, while USB is hot-pluggable. As a result, when Bluetooth is used over USB, the UART driver still be probed and drive BT_EN low, which causes the Bluetooth device on USB to be disconnected. Configure BT_EN as a GPIO hog so that it is controlled by the platform instead of the UART driver, preventing BT over USB from being unintentionally powered down.
