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 v5: changes of dt-bindings suggested by Rob: 1. Modify compatible as - compatible : should be one of: "mediatek,mt-2701" ... followed by "mediatek,mtk-musb" 2. Add usb connector child node changes of DTS: 1. Add usb connector child node changes of driver suggested by Bin: 1. Replace musb_readb() with musb_clearb() to clear dma pending interrupts 2. Replace musb_readb() with musb_clearb() to clear common/tx/rx pending interrupts 3. Make musb_clearb/w() return the value of musb_readb/w() changes in v4: changes of dt-bindings suggested by Sergei: 1. String alignment changes of driver suggested by Tony and Bin: 1. Add a new patch for set/get_toggle() 2. Add a new patch for noirq type of dma 3. Add a new patch musb_clearb/w() 4. Abondon patch "usb: musb: Delete the const attribute of addr parameter in readb/w/l hooks" changes in v3: changes of driver suggested by Bin: 1. Add a new patch for musb_readb/w/l() to remove const attribute 2. Use is_out as function parameter in set_toggle/get_toggle() hooks 3. Remove 'u8/u16 data' parameter in clearb/w() hooks 4. Remove musb_default_clearb/w() 5. Replace musb_readb/w() with musb_clearb/w() to clear pending interrupts 6. Add comments to clearb/w() hooks 7. Replace musb_save_toggle() with musb->io.get_toggle() 8. Replace musb_set_toggle() with musb->io.set_toggle() 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.
