This patchset is composed with : - bindings of the PHYs - bindings of the USB Control Glue - PHY Drivers - USB Control Glue driver Device Tree nodes will be added in a separate patchset. The Amlogic G12A USB Complex is composed of : - 2 USB Controllers : * DWC3 for USB2 and USB3 Host functionality * DWC2 for USB2 Peripheral functionality - 2 USB2 OTG PHYs, only a single one will be routed to either DWC2 to DWC3 - 1 USB3 PHY shared with PCIE funcionnality - A Glue to control PHY routing, setup and OTG detection The Glue configures the UTMI 8bit interfaces for the USB2 PHYs, including routing of the OTG PHY between the DWC3 and DWC2 controllers, and setups the on-chip OTG mode selection for this PHY. This drivers supports the on-probe setup of the OTG mode, and manually via the USB Role interface. The IRQ mode change detect is yet to be added in a future patchset, mainly due to lack of hardware to validate on. Changes since v1 at [0]: - USB2 PHY Bindings: collected tags and updated commit log - USB3/PCIE PHY Bindings: collected tag and updated reset list - DWC2 Compatible: collected tags - DWC3 Glue Bindings: - removed clock-names and reset-names for single entries - removed ports graph for PHYs and replaced by phys list with phy-names - added dr_mode and optional vbus-supply - fixed example - USB2 PHY Driver: removed USB_SUPPORT and otg.h include - USB3/PCIE PHY Driver: removed USB_SUPPORT, fixed comment and unused reg variable - USB Glue Driver: - Moved debugfs I/F to USB_ROLE_SWITCH framework - Integrated USB Glue Control Registers offset - Removed of graph parsing to use devm_phy_optional_get() - Fixed PHY mode handling and OTG switching - Simplified PHY calls by removing the NULL test - Added optional vbus regulator handling [1] https://lkml.kernel.org/r/20190212151413.24632-1-narmstrong@baylibre.com Neil Armstrong (8): dt-bindings: phy: Add Amlogic G12A USB2 PHY Bindings dt-bindings: phy: Add Amlogic G12A USB3+PCIE Combo PHY Bindings dt-bindings: usb: dwc2: Add Amlogic G12A DWC2 Compatible dt-bindings: usb: dwc3: Add Amlogic G12A DWC3 Glue Bindings phy: amlogic: add Amlogic G12A USB2 PHY Driver phy: amlogic: Add Amlogic G12A USB3 + PCIE Combo PHY Driver usb: dwc2: Add Amlogic G12A DWC2 Params usb: dwc3: Add Amlogic G12A DWC3 glue .../bindings/phy/meson-g12a-usb2-phy.txt | 22 + .../bindings/phy/meson-g12a-usb3-pcie-phy.txt | 22 + .../devicetree/bindings/usb/amlogic,dwc3.txt | 88 +++ .../devicetree/bindings/usb/dwc2.txt | 1 + drivers/phy/amlogic/Kconfig | 22 + drivers/phy/amlogic/Makefile | 2 + drivers/phy/amlogic/phy-meson-g12a-usb2.c | 190 ++++++ .../phy/amlogic/phy-meson-g12a-usb3-pcie.c | 411 ++++++++++++ drivers/usb/dwc2/params.c | 12 + drivers/usb/dwc3/Kconfig | 10 + drivers/usb/dwc3/Makefile | 1 + drivers/usb/dwc3/dwc3-meson-g12a.c | 601 ++++++++++++++++++ 12 files changed, 1382 insertions(+) create mode 100644 Documentation/devicetree/bindings/phy/meson-g12a-usb2-phy.txt create mode 100644 Documentation/devicetree/bindings/phy/meson-g12a-usb3-pcie-phy.txt create mode 100644 drivers/phy/amlogic/phy-meson-g12a-usb2.c create mode 100644 drivers/phy/amlogic/phy-meson-g12a-usb3-pcie.c create mode 100644 drivers/usb/dwc3/dwc3-meson-g12a.c -- 2.20.1
