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.
