Add support for the PHYs and controllers used for USB on SM8750 SoCs. --- Changes in v6: - Change readl_relaxed/writel_relaxed calls to just readl/writel in the readback function - Updated languange in the defconfig commit to specify SM8750 as a Qualcomm SoC - Link to v5: https://lore.kernel.org/r/20250421-sm8750_usb_master-v5-0-25c79ed01d02@oss.qualcomm.com Changes in v5: - Removed refclk_src from the QMP PHY driver as that is no longer used. - The decision to move the TCSR clkref property from controller --> phy node was made in v4, and the refclk_src was a lingering change that was meant to be removed. CXO is the parent clock for TCSR clkref, so CXO clk will be voted for as well. - Relocate the SM8750 compatible within the qcom,dwc3 bindings. This is to take into account the change in clock list. - Link to v4: https://lore.kernel.org/r/20250409-sm8750_usb_master-v4-0-6ec621c98be6@oss.qualcomm.com Changes in v4: - Made some fixups to the M31 eUSB2 driver - Moved TCSR refclk_en to the QMP PHY DT node - Link to v3: https://lore.kernel.org/r/20250324-sm8750_usb_master-v3-0-13e096dc88fd@quicinc.com Changes in v3: - Split platform DTs into separate commits. - Fixed up M31 eUSB2 PHY driver with feedback received. - Reordered DT properties based on feedback. - Rewrote commit message for enabling EUSB driver. - Link to v2: https://lore.kernel.org/r/20250304-sm8750_usb_master-v2-0-a698a2e68e06@quicinc.com Changes in v2: - Added new QMP PHY register definitions for v8 based QMP phys. - Made changes to clean up some code in the M31 eUSB2 PHY driver based on feedback received. - Added bulk regulator operations in M31 eUSB2 PHY, to ensure that both the vdd and vdda12 regulators are properly voted for. - Removed external references to other dt bindings in M31 example for the DT bindings change. - Split DT patches between SoC and plaform changes, as well as the PHY subsystem Kconfig changes when introducing the M31 eUSB2 PHY. - Added orientation switch and port definitions in the DT changes.EDITME: describe what is new in this series revision. - Link to v1: https://lore.kernel.org/r/20250113-sm8750_usb_master-v1-0-09afe1dc2524@quicinc.com --- Melody Olvera (2): dt-bindings: usb: qcom,dwc3: Correct the SM8750 compatible arm64: defconfig: Add M31 eUSB2 PHY config Wesley Cheng (8): dt-bindings: phy: qcom,sc8280xp-qmp-usb43dp-phy: Add SM8750 to QMP PHY dt-bindings: phy: Add the M31 based eUSB2 PHY bindings phy: qcom: qmp-combo: Add new PHY sequences for SM8750 phy: qcom: Update description for QCOM based eUSB2 repeater phy: qcom: Add M31 based eUSB2 PHY driver arm64: dts: qcom: sm8750: Add USB support to SM8750 SoCs arm64: dts: qcom: sm8750: Add USB support for SM8750 MTP platform arm64: dts: qcom: sm8750: Add USB support for SM8750 QRD platform .../bindings/phy/qcom,m31-eusb2-phy.yaml | 79 +++++ .../phy/qcom,sc8280xp-qmp-usb43dp-phy.yaml | 2 + .../devicetree/bindings/usb/qcom,dwc3.yaml | 2 +- arch/arm64/boot/dts/qcom/sm8750-mtp.dts | 24 ++ arch/arm64/boot/dts/qcom/sm8750-qrd.dts | 24 ++ arch/arm64/boot/dts/qcom/sm8750.dtsi | 164 +++++++++++ arch/arm64/configs/defconfig | 1 + drivers/phy/qualcomm/Kconfig | 16 +- drivers/phy/qualcomm/Makefile | 1 + drivers/phy/qualcomm/phy-qcom-m31-eusb2.c | 325 +++++++++++++++++++++ drivers/phy/qualcomm/phy-qcom-qmp-combo.c | 221 ++++++++++++++ drivers/phy/qualcomm/phy-qcom-qmp-pcs-usb-v8.h | 38 +++ drivers/phy/qualcomm/phy-qcom-qmp-pcs-v8.h | 32 ++ drivers/phy/qualcomm/phy-qcom-qmp-qserdes-com-v8.h | 64 ++++ .../phy/qualcomm/phy-qcom-qmp-qserdes-txrx-v8.h | 68 +++++ drivers/phy/qualcomm/phy-qcom-qmp.h | 5 + 16 files changed, 1062 insertions(+), 4 deletions(-) --- base-commit: fefff2755f2aa4125dce2a1edfe7e545c7c621f2 change-id: 20241223-sm8750_usb_master-f27aed7f6d40 Best regards,
