The Amlogic AXG is close to the GXL Glue but with a single OTG PHY. It needs the same init sequence as GXL & GXM, but it seems it doesn't need the host disconnect bit. The Glue driver reuses the already implemented GXL & GXM work. The USB2 PHY driver needs a slight tweak to keep the OTG detection working. Changes since v1 at [1]: - s/close from/close to/g - collected review tags - added small comment about phy management in patch 3 - removed status = "okay" in patch 4 - removed invalid phy-supply of phy1 in patch 5 [1] http://lore.kernel.org/r/20200909160409.8678-1-narmstrong@xxxxxxxxxxxx Neil Armstrong (5): phy: amlogic: phy-meson-gxl-usb2: keep ID pull-up even in Host mode dt-bindings: usb: amlogic,meson-g12a-usb-ctrl: add the Amlogic AXG Families USB Glue Bindings usb: dwc-meson-g12a: Add support for USB on AXG SoCs arm64: dts: meson-axg: add USB nodes arm64: dts: meson-axg-s400: enable USB OTG .../usb/amlogic,meson-g12a-usb-ctrl.yaml | 22 +++++++- .../arm64/boot/dts/amlogic/meson-axg-s400.dts | 6 +++ arch/arm64/boot/dts/amlogic/meson-axg.dtsi | 50 +++++++++++++++++++ drivers/phy/amlogic/phy-meson-gxl-usb2.c | 3 +- drivers/usb/dwc3/dwc3-meson-g12a.c | 18 +++++++ 5 files changed, 97 insertions(+), 2 deletions(-) -- 2.22.0
