USB work mode is peripheral and using USB 2.0 PHY in VisionFive 2 board. The patch has been tested on the VisionFive 2 board. This patchset should be applied after the patchset [1], [2] and [3]: [1] https://patchwork.kernel.org/project/linux-riscv/cover/20230518101234.143748-1-xingyu.wu@starfivetech.com/ [2] https://patchwork.kernel.org/project/linux-clk/cover/20230512022036.97987-1-xingyu.wu@starfivetech.com [3] https://patchwork.kernel.org/project/linux-phy/cover/20230412084540.295411-1-changhuang.liang@starfivetech.com/ This patchset is base on v6.4-rc1 patch 1 is usb phy dt-binding document. patch 2 is Pcie PHY dt-binding document. patch 3 is USB 2.0 PHY driver. patch 4 is PCIe PHY driver. patch 5 is usb dt-binding document. patch 6 is the wrapper module driver of Cadence USB3. USB controller IP is Cadence USB3. patch 7 is USB device tree configuration. previous version --- version 1 patchset are split to different kernel organization. It is incorrect. But they were sent, and Emil sent comments. I think I should reserve them in cover-letter. To read the change records and previous version, please start with version 2. v1: https://patchwork.kernel.org/project/linux-usb/cover/20230306095212.25840-1-minda.chen@starfivetech.com/ v2: https://patchwork.kernel.org/project/linux-usb/cover/20230308082800.3008-1-minda.chen@starfivetech.com/ v3: https://patchwork.kernel.org/project/linux-usb/cover/20230315104411.73614-1-minda.chen@starfivetech.com/ v4: https://patchwork.kernel.org/project/linux-usb/cover/20230406015216.27034-1-minda.chen@starfivetech.com/ v5: https://patchwork.kernel.org/project/linux-usb/cover/20230420110052.3182-1-minda.chen@starfivetech.com/ changes v6: 1. (patch 3) remove the platform remove function. 2. (patch 4) - add switch to pcie mode function. - remove the redundant init/exit function. 3. (patch 5) - dts split to wrapper layer and cdns node. The codes are like v3. - add cdns3 sub node dts-binding references. 4. (patch 6) For stg-syscon iomem 0x10240000 - 0x10240010 actually is belonged to usb, so USB contain its own registers. So do not merge the dts node. The codes are like v3. - remove the cdns3_platform_add function. - remove phy ops because cdns3 contain all the phy ops. - runtime suspend function just shutdown the clocks. 5. (patch 7) - add cdns3 subnode again. v5: 1. (patch 1) set correct model name and commit title. 2. (patch 2) change to '-item' in syscon property. change commit title. 3. (patch 5) - change to '-item' in syscon configure. - change commit title and doc title. 4. (patch 6) - add clk and phy deinit function - add clk deinit function if phy init failed. - coding style changes and other format changes. v4: 1. (patch 1) split PCIe PHY dt-binding doc to patch 2. 2. (patch 2) PCIe PHY add stg and sys con configuration to dt-binding doc. 3. (patch 3) - split PCIe PHY driver to patch 4. - replace dr_mode to phy mode in jh7110_usb2_phy. 4. (patch 4) - Makefile and Kconfig sorted by alphabet sequence. - Add PCIe PHY stg and syscon PHY connection configuration for USB 3.0. 5. (patch 5) - commit message changed. - merge wrapper dts node and cdns3 node in example. - Add interrupts, reg, phy and dr_mode in property. - Add reset-name in property example. 6. (patch 6) - For dts node is merged, Using platform_device_alloc and platform_device_add to generate cadence sub device. - IOMEM and IRQ resource are passed to Cadence sub device. - Add PHY ops process for PHY dts setting can not be passed to Cadence USB driver. - remove the stg and sys USB 3.0 PHY configuration. - Change the suspend clock reset and clock enable sequence. - Get all reset and clock resources before enable them in cdns_clk_rst_init. - commit message changed. 7. (patch 7) - merge wrapper dts node and cdns3 node in usb dts. - move the stg and sys USB 3.0 PHY confiuration to PCIe PHY dts node. - commit message changed. - Add reset-names dts. v3: 1. Add patch 1 - 4. Add USB PHY driver and dt-binding doc. USB PHY codes are moved to patch 3 and patch 4. 2. (patch 5) - USB wrapper module dts document is moved to usb directory. - Remove the 'dr_mode' and 'starfive,usb2-only' setting. - Some dts format changes. dts binding check pass. 3. (patch 6) - Remove the PHY codes. - Search 'dr_mode' and phy setting from Cadence subnode. 4. (patch 7) - Add USB PHY dts configurion. - 'dr_mode' is moved to Cadence controller submode. v2: 1. (patch 5) dt-binding changes. The document example is the same as dts config. 2. (patch 6) using dev_err_probe and syscon_regmap_lookup_by_phandle_args function. Some formats changes 3. (patch 7) dts nodes sorted by the address after @ Minda Chen (7): dt-bindings: phy: Add StarFive JH7110 USB PHY dt-bindings: phy: Add StarFive JH7110 PCIe PHY phy: starfive: Add JH7110 USB 2.0 PHY driver phy: starfive: Add JH7110 PCIE 2.0 PHY driver dt-bindings: usb: Add StarFive JH7110 USB controller usb: cdns3: Add StarFive JH7110 USB driver riscv: dts: starfive: Add USB dts configuration for JH7110 .../phy/starfive,jh7110-pcie-phy.yaml | 58 +++++ .../bindings/phy/starfive,jh7110-usb-phy.yaml | 50 ++++ .../bindings/usb/starfive,jh7110-usb.yaml | 115 ++++++++ MAINTAINERS | 14 + .../jh7110-starfive-visionfive-2.dtsi | 5 + arch/riscv/boot/dts/starfive/jh7110.dtsi | 53 ++++ drivers/phy/starfive/Kconfig | 21 ++ drivers/phy/starfive/Makefile | 2 + drivers/phy/starfive/phy-jh7110-pcie.c | 204 +++++++++++++++ drivers/phy/starfive/phy-jh7110-usb.c | 150 +++++++++++ drivers/usb/cdns3/Kconfig | 11 + drivers/usb/cdns3/Makefile | 1 + drivers/usb/cdns3/cdns3-starfive.c | 246 ++++++++++++++++++ 13 files changed, 930 insertions(+) create mode 100644 Documentation/devicetree/bindings/phy/starfive,jh7110-pcie-phy.yaml create mode 100644 Documentation/devicetree/bindings/phy/starfive,jh7110-usb-phy.yaml create mode 100644 Documentation/devicetree/bindings/usb/starfive,jh7110-usb.yaml create mode 100644 drivers/phy/starfive/phy-jh7110-pcie.c create mode 100644 drivers/phy/starfive/phy-jh7110-usb.c create mode 100644 drivers/usb/cdns3/cdns3-starfive.c base-commit: ac9a78681b921877518763ba0e89202254349d1b -- 2.17.1
