This patchset introduces the USB Host driver for i.MX28 CPU, utilising the
generic USB PHY infrastructure. 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!)
V6: Do PHY-specific job inside the PHY driver
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
