qcom: Add support for IQ-9075-evk board

This series: Add support for Qualcomm's iq9-evk board using QCS9075 SOC. QCS9075 is compatible IoT-industrial grade variant of SA8775p SOC. Unlike QCS9100, it doesn't have safety monitoring feature of Safety-Island(SAIL) subsystem, which affects thermal management. In QCS9100 SOC, the safety subsystem monitors all thermal sensors and does corrective action for each subsystem based on sensor violation to comply safety standards. But as QCS9075 is non-safe SOC it requires conventional thermal mitigation for thermal management. In this series thermal mitigation changes are not included as it needs more discussion whether to include the change in DT or in drivers. Below are detailed informations on IQ-9075-evk HW: ------------------------------------------------------ QCS9075 SOM is stacked on top of IQ-9075-evk board. On top of IQ-9075-evk board additional mezzanine boards can be stacked in future. IQ-9075-evk is single board supporting these peripherals: - Storage: 2 × 128 GB UFS, micro-SD card, EEPROMs for MACs, eMMC on mezzanine card - Audio/Video, Camera & Display ports - Connectivity: RJ45 2.5GbE, WLAN/Bluetooth, CAN/CAN-FD - Sensors: IMU - PCIe ports - USB & UART ports Currently basic features are enabled to support 'boot to shell'. --- Changelog: v7: - Add UFS support along with l4c regulator from [1] - Remove "qcom,qcs9075-som" compatible and keep only SOM dtsi file - Increase camera pil size - Update commit text as per new changes - v6-link: [2] [1] https://lore.kernel.org/all/20250513084309.10275-1-quic_sayalil@quicinc.com/ [2] https://lore.kernel.org/all/20250429054906.113317-1-quic_wasimn@quicinc.com/ Pratyush Brahma (1): arm64: dts: qcom: iq9: Introduce new memory map for qcs9100/qcs9075 Rakesh Kota (1): arm64: dts: qcom: Add support L4C LDO for qcs9075 IQ-9075-EVK Sayali Lokhande (1): arm64: dts: qcom: Add UFS support for qcs9075 IQ-9075-EVK Wasim Nazir (3): dt-bindings: arm: qcom: Add bindings for QCS9075 SOC based board arm64: dts: qcom: qcs9075: Introduce QCS9075 SOM arm64: dts: qcom: Add support for qcs9075 IQ-9075-EVK .../devicetree/bindings/arm/qcom.yaml | 7 + arch/arm64/boot/dts/qcom/Makefile | 1 + .../boot/dts/qcom/iq9-reserved-memory.dtsi | 113 +++++++ .../boot/dts/qcom/qcs9075-iq-9075-evk.dts | 295 ++++++++++++++++++ arch/arm64/boot/dts/qcom/qcs9075-som.dtsi | 10 + 5 files changed, 426 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/iq9-reserved-memory.dtsi create mode 100644 arch/arm64/boot/dts/qcom/qcs9075-iq-9075-evk.dts create mode 100644 arch/arm64/boot/dts/qcom/qcs9075-som.dtsi base-commit: 8566fc3b96539e3235909d6bdda198e1282beaed -- 2.49.0
