However, there are a couple extra register bits, and the CFIFO register 8-bit access works a little different (weird, no idea why). There is a dedicated DMAC for the RZ/A2 USB Device HW, but we have not been able to reliably get that working yet, so device operation is pio only at the moment. On the RZ/A2M eval board, both USB channels can be used as either host or device. But, it's not set up for otg (ie, there are jumpers and separate connectors). Therefore, below is an example of what it would look like to enable USB channel 0 as a device instead of a host. &usb2_phy0 { pinctrl-names = "default"; pinctrl-0 = <&usb0_pins>; renesas,uses_usb_x1; dr_mode = "peripheral"; status = "okay"; }; &usbhs0 { status = "okay"; }; Chris Brandt (10): phy: renesas: rcar-gen3-usb2: Add uses_usb_x1 option dt-bindings: rcar-gen3-phy-usb2: Document uses_usb_x1 phy: renesas: rcar-gen3-usb2: Check dr_mode when not using OTG dt-bindings: rcar-gen3-phy-usb2: Document dr_mode dt-bindings: rcar-gen3-phy-usb2: Add r7s9210 support usb: renesas_usbhs: Add support for RZ/A2 dt-bindings: usb: renesas_usbhs: Add support for r7s9210 ARM: dts: r7s9210: Add USB Host support ARM: dts: r7s9210: Add USB Device support ARM: dts: r7s9210-rza2mevb: Add USB host support .../devicetree/bindings/phy/rcar-gen3-phy-usb2.txt | 15 +++- .../devicetree/bindings/usb/renesas_usbhs.txt | 2 + arch/arm/boot/dts/r7s9210-rza2mevb.dts | 37 +++++++++ arch/arm/boot/dts/r7s9210.dtsi | 88 ++++++++++++++++++++++ drivers/phy/renesas/phy-rcar-gen3-usb2.c | 16 +++- drivers/usb/renesas_usbhs/Makefile | 2 +- drivers/usb/renesas_usbhs/common.c | 27 +++++-- drivers/usb/renesas_usbhs/common.h | 13 ++++ drivers/usb/renesas_usbhs/fifo.c | 8 +- drivers/usb/renesas_usbhs/rza.h | 1 + drivers/usb/renesas_usbhs/rza2.c | 82 ++++++++++++++++++++ include/linux/usb/renesas_usbhs.h | 1 + 12 files changed, 277 insertions(+), 15 deletions(-) create mode 100644 drivers/usb/renesas_usbhs/rza2.c -- 2.16.1
