drivers: phy: add generic PHY framework The PHY framework provides a set of APIs for the PHY drivers to create/destroy a PHY and APIs for the PHY users to obtain a reference to the PHY with or without using phandle. For dt-boot, the PHY drivers should also register *PHY provider* with the framework. PHY drivers should create the PHY by passing id and ops like init, exit, power_on and power_off. This framework is also pm runtime enabled. The documentation for the generic PHY framework is added in Documentation/phy.txt and the documentation for dt binding can be found at Documentation/devicetree/bindings/phy/phy-bindings.txt Cc: Tomasz Figa <t.figa@samsung.com> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Acked-by: Felipe Balbi <balbi@ti.com> Tested-by: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Generic PHY support.
This framework is designed to provide a generic interface for PHY
devices present in the kernel. This layer will have the generic
API by which phy drivers can create PHY using the phy framework and
phy users can obtain reference to the PHY. All the users of this
framework should select this config.
usb: phy: omap-usb2: use the new generic PHY framework Used the generic PHY framework API to create the PHY. Now the power off and power on are done in omap_usb_power_off and omap_usb_power_on respectively. The omap-usb2 driver is also moved to driver/phy. However using the old USB PHY library cannot be completely removed because OTG is intertwined with PHY and moving to the new framework will break OTG. Once we have a separate OTG state machine, we can get rid of the USB PHY library.

Enable this to support the transceiver that is part of SOC. This
driver takes care of all the PHY functionality apart from comparator.
The USB OTG controller communicates with the comparator using this
driver.
