[PATCH v2 0/5] Generic PHY Framework
Added a generic PHY framework that 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. To obtain a reference to the PHY without using phandle, the platform specfic intialization code (say from board file) should have already called phy_bind with the binding information. The binding information consists of phy's device name, phy user device name and an index. The index is used when the same phy user binds to mulitple phys. This framework will be of use only to devices that uses external PHY (PHY functionality is not embedded within the controller). The intention of creating this framework is to bring the phy drivers spread all over the Linux kernel to drivers/phy to increase code re-use and to increase code maintainability. Comments to make PHY as bus wasn't done because PHY devices can be part of other bus and making a same device attached to multiple bus leads to bad design. Changes from v1: * Added Documentation for the PHY framework * Added few more APIs mostly w.r.t devres * Modified omap-usb2 and twl4030 to make use of the new framework Did USB enumeration testing in panda and beagle.
