both isp1301-omap and fsl_usb2_otg drivers depend on usb_bus_start_enum() which is only defined if CONFIG_USB != n. There is a problem, however, where both those drivers could be statically linked, while CONFIG_USB=m. Fix the problem by fixing driver dependency.

Commit bd27fa44 (usb: phy: generic: Don't use regulator framework for RESET line) introduced regression: All users of usb_nop_xceiv_register() will fail because there is no platform data and the default reset GPIO is 0 which is a valid GPIO.

instead of having each user of generic phy find out about its own resources and pass it to the core layer, have th core layer itself figure that out. It's as simple as moving a piece of code around. This fixes a big regression caused during the merge window where am335x-based platforms wouldn't be able to probe their PHY driver. Signed-off-by: NFelipe Balbi <balbi@ti.com>

Commit [4d175f34: usb: phy: nop: Defer clock prepare until PHY init] removed a goto reaching behind a “return ret” at the end of the function thus removing the only possible way that statement could be reached, and so rendering it a dead code.

Modelling the RESET line as a regulator supply wasn't a good idea as it kind of abuses the regulator framework and also makes adaptation code more complex. Instead, manage the RESET gpio line directly in the driver. Update the device tree binding information. This also makes us easy to migrate to a dedicated GPIO RESET controller whenever it becomes available. Signed-off-by: NRoger Quadros <rogerq@ti.com> Signed-off-by: NFelipe Balbi <balbi@ti.com>

omap_get_control_dev() is being deprecated as it doesn't support multiple instances. As control device is present only from OMAP4 onwards which supports DT only, we use phandles to get the reference to the control device.

Add support for new device types and in the process rid of "ti,type" device tree property. The correct type of device will be determined from the compatible string instead. Introduce a compatible string for each device type. At the moment we support 4 types OTGHS, USB2, PIPE3 (e.g. USB3) and DRA7USB2. Update DT binding information to reflect these changes. Also get rid of omap_control_usb3_phy_power(). Just one function i.e. omap_control_usb_phy_power() will now take care of all PHY types.

Used the generic PHY framework API to create the PHY. For powering on and powering off the PHY, power_on and power_off ops are used. Once the MUSB OMAP glue is adapted to the new framework, the suspend and resume ops of usb phy library will be removed. Also twl4030-usb driver is moved to drivers/phy/. However using the old usb phy library cannot be completely removed because otg is intertwined with phy and moving to the new framework completely will break otg. Once we have a separate otg state machine, we can get rid of the usb phy library.
