The driver can be configured as Dual-Role Device (DRD), Peripheral Only and Host Only modes. This has beed tested on MT2701 with a variety of devices in host mode and with the f_mass gadget driver in peripheral mode, plugging otg cables in/out a lot of times in all possible imaginable plug orders. changes in v2: changes of dt-bindings suggested by Rob and Bin: 1. Modify DRC to DRD 2. Drop the "-musb" in compatible 3. Remove phy-names 4. Add space after comma in clock-names dtsi: 1. Remove phy-names changes of driver suggested by Bin: 1. Add a new patch for musb_set_toggle 2. Add summarize of MediaTek musb controller differences in the commit log 3. Abondon patch "usb: musb: Move musbhsdma macro definition to musb_dma.h" 4. Add "|| COMPILE_TEST" in Kconfig 5. Add musb_clearb() and musb_clearw() hooks 6. Add get_toggle() and set_toggle() hooks 7. Replace musb_readl() with musb_readw() to read 16bit toggle register 8. Move MediaTek's private toggle registers from musb_regs.h to mediatek.c 9. Create musbhs_dma_controller_create_noirq() Min Guo (4): dt-bindings: usb: musb: Add support for MediaTek musb controller arm: dts: mt2701: Add usb2 device nodes usb: musb: Extract set toggle as a separate interface usb: musb: Add support for MediaTek musb controller .../devicetree/bindings/usb/mediatek,musb.txt | 43 ++ arch/arm/boot/dts/mt2701-evb.dts | 21 + arch/arm/boot/dts/mt2701.dtsi | 33 ++ drivers/usb/musb/Kconfig | 8 +- drivers/usb/musb/Makefile | 1 + drivers/usb/musb/mediatek.c | 617 +++++++++++++++++++++ drivers/usb/musb/musb_core.c | 69 +++ drivers/usb/musb/musb_core.h | 9 + drivers/usb/musb/musb_dma.h | 9 + drivers/usb/musb/musb_host.c | 35 +- drivers/usb/musb/musb_io.h | 6 + drivers/usb/musb/musbhsdma.c | 55 +- 12 files changed, 868 insertions(+), 38 deletions(-) create mode 100644 Documentation/devicetree/bindings/usb/mediatek,musb.txt create mode 100644 drivers/usb/musb/mediatek.c Tested-by: Ryder Lee
