Introduce support for the SC7280 platform and specifically the RB3 Gen 2 development board.
The RB3 Gen 2 is the latest robotics board from Qualcomm, featuring a QCM6490 SoC (the same SoC found in the Fairphone 5), 6GB of RAM, and 128GB of UFS storage, as well as a whole lot of I/O. Most of the I/O is attached via a custom PCIe bridge chip, and as such is not yet supported. However it is possible to boot from USB via the Type-C port, which is hardcoded to host mode for this initial support. USB support additionally requires this patch: https://lore.kernel.org/u-boot/20240423141551.2410199-1-caleb.conno...@linaro.org/ --- Caleb Connolly (7): clk/qcom: add initial clock driver for sc7280 dts: qcs6490-rb3gen2-u-boot: add override dtsi dts: qcs6490-rb3gen2-u-boot: USB host mode iommu: qcom-smmu: add sc7280-smmu-500 compatible qcom_defconfig: enable SC7280 clocks configs: add qcm6490_defconfig doc: board/qualcomm: document rb3gen2 building/flashing arch/arm/dts/qcs6490-rb3gen2-u-boot.dtsi | 28 +++++++ configs/qcm6490_defconfig | 18 +++++ configs/qcom_defconfig | 1 + doc/board/qualcomm/rb3gen2.rst | 53 +++++++++++++ drivers/clk/qcom/Kconfig | 8 ++ drivers/clk/qcom/Makefile | 1 + drivers/clk/qcom/clock-qcom.h | 1 + drivers/clk/qcom/clock-sc7280.c | 132 +++++++++++++++++++++++++++++++ drivers/iommu/qcom-hyp-smmu.c | 1 + 9 files changed, 243 insertions(+) --- change-id: 20240809-b4-rb3gen2-87bd866abde1 base-commit: 428e11e6e36aa0a13f85961c64af24751c4d1bb7 // Caleb (they/them)
