This patchset adds support for the eUSB2 repeater found in pmic PM8550B, used along with SM8550. 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/20230208183421.2874423-1-abel.vesa@xxxxxxxxxx/ Changes since v4: * added Krzysztof's R-b tag got patch #1 and A-b tag to patch #3 Changes since v3: * This time is a normal patchset, rather than an RFC 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 | 52 ++++ 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, 361 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
