This patchset is composed with : - bindings of the PHY - bindings of the USB Control Glue - PHY Driver - USB Control Glue driver - dts of the PHY - dts of the USB Controller The Amlogic A1 USB Complex is composed of : - 1 DWC3 USB controller for USB2 Host functionality - 1 USB2 PHY for USB2 Host functionality The USB Control Glue setups the clocks and the reset about DWC3 USB controller, and binds to the USB2 PHY. It also configures the 8bit UTMI interfaces for the USB2 PHY, including setting USB2 phy mode. The USB2 PHY driver initializes the phy analog settings, phy PLL setup and phy tuning. This patchset is based on A1 clock/power domain/reset series at [0]. Changes since v1:[1] - integrate glue and phy drivers into g12a's Changes since v2:[2] - modify amlogic,meson-g12a-usb-ctrl.yaml with dt_binding_check tool - phy/glue driver use of_device_get_match_data to distinguish A1 from G12A Changes since v3:[3] - fix bindings mistakes of the PHY according Rob's comments - fix bindings mistakes of the USB Control Glue according Rob's comments - phy driver add xtal_usb_phy clock which moved from glue driver - glue driver use otg_mode instead of soc_id to support otg function [0] https://patchwork.kernel.org/project/linux-amlogic/list/?series=185477 https://patchwork.kernel.org/project/linux-amlogic/list/?series=180055 https://patchwork.kernel.org/project/linux-amlogic/list/?series=189643 [1] : https://lore.kernel.org/linux-amlogic/1574405757-76184-1-git-send-email-hanjie.lin@xxxxxxxxxxx [2] : https://lore.kernel.org/linux-amlogic/1576636944-196192-1-git-send-email-hanjie.lin@xxxxxxxxxxx [3] : https://lore.kernel.org/linux-amlogic/1577428606-69855-1-git-send-email-hanjie.lin@xxxxxxxxxxx Hanjie Lin (6): dt-bindings: phy: Add Amlogic A1 USB2 PHY Bindings dt-bindings: usb: dwc3: Add the Amlogic A1 Family DWC3 Glue Bindings phy: amlogic: Add Amlogic A1 USB2 PHY Driver usb: dwc3: Add Amlogic A1 DWC3 glue arm64: dts: meson: a1: Enable USB2 PHY arm64: dts: meson: a1: Enable DWC3 controller .../bindings/phy/amlogic,meson-a1-usb2-phy.yaml | 56 ++++++++++++ .../bindings/usb/amlogic,meson-g12a-usb-ctrl.yaml | 11 +++ arch/arm64/boot/dts/amlogic/meson-a1.dtsi | 43 ++++++++++ drivers/phy/amlogic/phy-meson-g12a-usb2.c | 99 +++++++++++++++------- drivers/usb/dwc3/dwc3-meson-g12a.c | 99 ++++++++++++++++------ 5 files changed, 250 insertions(+), 58 deletions(-) create mode 100644 Documentation/devicetree/bindings/phy/amlogic,meson-a1-usb2-phy.yaml -- 2.7.4
