Also added is glue code for CI13xxx driver, to allow device mode. This patchset still does NOT support OTG mode, the device/host mode is selected via platform data. V2: Introduce stub imx-usb driver that then registers the PHY and EHCI drivers. V3: Add the HCD on demand based on the PHY's state (only add HCD if it's host). Currently, only the HOST mode is supported. V4: * Introduce ci13xxx gadget glue * Reorder patches in a more sensible order * Introduce platform data, containing VBUS GPIO and port mode (device/gadget) * Rename imx-usb to imx-otg * Drop mx28evk usb host patch * Use more devm_ function * Rework the mxs-phy to register the same interrupt as ehci-mxs (and effectivelly kill bogus otg_set_vbus() call from ehci-mxs ; use standard ehci irq handling in ehci-mxs) V5: * Finally move OTG IRQ handling into imx-otg * Move imx_otg_set_{host,peripheral}() into imx-otg * Move imx_otg_work() into imx-otg driver (now it all makes sense, yay!) Marek Vasut (11): MXS: Make clk_disable return integer MXS: Add USB EHCI and USB PHY clock handling MXS: Fixup i.MX233 USB base address name MXS: Add data shared between imx-otg and EHCI driver MXS: Modify the ci13xxx_udc to avoid adding UDC MXS: Add small registration glue for ci13xxx_udc MXS: Add separate MXS EHCI HCD driver MXS: Add imx-otg driver MXS: Add USB PHY driver MXS: Add platform registration hooks for USB EHCI MXS: Enable USB on M28EVK arch/arm/mach-mxs/Kconfig | 2 + arch/arm/mach-mxs/clock-mx28.c | 28 +- arch/arm/mach-mxs/devices-mx28.h | 5 + arch/arm/mach-mxs/devices/Kconfig | 3 + arch/arm/mach-mxs/devices/Makefile | 1 + arch/arm/mach-mxs/devices/platform-usb.c | 85 ++++ arch/arm/mach-mxs/include/mach/clock.h | 2 +- arch/arm/mach-mxs/include/mach/devices-common.h | 13 + arch/arm/mach-mxs/include/mach/mx23.h | 8 +- arch/arm/mach-mxs/mach-m28evk.c | 21 + drivers/usb/gadget/Kconfig | 17 + drivers/usb/gadget/Makefile | 1 + drivers/usb/gadget/ci13xxx_mxs.c | 67 ++++ drivers/usb/gadget/ci13xxx_udc.c | 12 +- drivers/usb/gadget/ci13xxx_udc.h | 1 + drivers/usb/host/Kconfig | 7 + drivers/usb/host/ehci-hcd.c | 5 + drivers/usb/host/ehci-mxs.c | 178 +++++++++ drivers/usb/otg/Kconfig | 16 + drivers/usb/otg/Makefile | 2 + drivers/usb/otg/imx-otg.c | 473 +++++++++++++++++++++++ drivers/usb/otg/mxs-phy.c | 237 ++++++++++++ include/linux/usb/mxs-usb.h | 95 +++++ 23 files changed, 1266 insertions(+), 13 deletions(-) create mode 100644 arch/arm/mach-mxs/devices/platform-usb.c create mode 100644 drivers/usb/gadget/ci13xxx_mxs.c create mode 100644 drivers/usb/host/ehci-mxs.c create mode 100644 drivers/usb/otg/imx-otg.c create mode 100644 drivers/usb/otg/mxs-phy.c create mode 100644 include/linux/usb/mxs-usb.h Cc: Chen Peter-B29397 Cc: Detlev Zundel Cc: Fabio Estevam Cc: Li Frank-B20596 Cc: Lin Tony-B19295 Cc: Linux USB Cc: Sascha Hauer Cc: Shawn Guo Cc: Shawn Guo Cc: Stefano Babic Cc: Subodh Nijsure Cc: Tony Lin Cc: Wolfgang Denk -- 1.7.10
