Well it usually works if you plug the cable once, but as soon as you start replugging cables and mixing host adapter into the game it totally breaks and reboot is then needed. Host mode is especially broken, any replugs after musb has been in host mode result in dead port that needs reboot to recover. With this series I can switch host/peripheral cables any way I like and even suspend works with cable plugged with musb in peripheral mode! ("ARM: OMAP3: hwmod data: keep MIDLEMODE in force-standby for musb" is needed that was sent separately). This also fixes power drain when cable is plugged an no gadget driver is loaded. Changed since v1: - rebased on Felipe's testing branch - added locking for patch 4 to take care of possible races between work item and IRQ - changed patch 6 to only disable VBUS if not runtime suspended, otherwise we get data abort on OMAP3 Grazvydas Ignotas (7): usb: phy: twl4030-usb: don't enable PHY during init usb: phy: twl4030-usb: ignore duplicate events usb: phy: twl4030-usb: don't switch the phy on/off needlessly usb: phy: twl4030-usb: poll for ID disconnect usb: phy: twl4030-usb: check if vbus is driven by twl itself usb: musb: omap2430: turn off vbus on cable disconnect usb: musb: gadget: use platform callback to enable vbus drivers/usb/musb/musb_gadget.c | 5 +- drivers/usb/musb/omap2430.c | 1 + drivers/usb/phy/phy-twl4030-usb.c | 123 +++++++++++++++++++++++++++++-------- 3 files changed, 99 insertions(+), 30 deletions(-) -- 1.7.9.5
