Since there is no dedicated generic framework for eUSB2 repeaters, the most appropriate subsystem to model it is the generic phy. This patchset also adds support for such repeater to the eUSB2 PHY found in SM8550. Basically, the eUSB2 PHY will have its own "phy" which is actually a repeater. This patchset is based on the following patchset: https://lore.kernel.org/all/20230207114024.944314-1-abel.vesa@linaro.org Changes since v3: * This time is a normal patchset, rather than an RFC * reversed the order of patches 1 and 2, in order to make the repeater schema available for the pmic schema update Changes since v2: * moved the bindings qcom,spmi-pmic patch before the repeater schema patch in order to avoid the repeater schema validation failure due to phy pattern property not being found in qcom,spmi-pmic schema Changes since v1: * the repeater driver is implemented now as a PHY rather than adding a new generic framework for USB repeaters Abel Vesa (5): dt-bindings: phy: Add qcom,snps-eusb2-repeater schema file dt-bindings: mfd: qcom,spmi-pmic: Add pattern property for phy dt-bindings: phy: qcom,snps-eusb2-phy: Add phys property for the repeater phy: qcom: Add QCOM SNPS eUSB2 repeater driver arm64: dts: qcom: sm8550-mtp: Add eUSB2 repeater node Neil Armstrong (2): phy: qcom: phy-qcom-snps-eusb2: Add support for eUSB2 repeater arm64: dts: qcom: pm8550b: Add eUSB2 repeater node .../bindings/mfd/qcom,spmi-pmic.yaml | 4 + .../bindings/phy/qcom,snps-eusb2-phy.yaml | 5 + .../phy/qcom,snps-eusb2-repeater.yaml | 48 ++++ arch/arm64/boot/dts/qcom/pm8550b.dtsi | 6 + arch/arm64/boot/dts/qcom/sm8550-mtp.dts | 7 + drivers/phy/qualcomm/Kconfig | 9 + drivers/phy/qualcomm/Makefile | 1 + .../phy/qualcomm/phy-qcom-eusb2-repeater.c | 259 ++++++++++++++++++ drivers/phy/qualcomm/phy-qcom-snps-eusb2.c | 19 +- 9 files changed, 357 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/phy/qcom,snps-eusb2-repeater.yaml create mode 100644 drivers/phy/qualcomm/phy-qcom-eusb2-repeater.c -- 2.34.1
