[PATCH 00/15] 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.

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.

If the PHY driver has to send notification on connect/disconnect, the PHY
driver should make use of the extcon framework. Using this susbsystem
to use extcon framwork will have to be analysed.

Exynos MIPI CSIS/DSIM PHY and Displayport PHY have started using this
framework. Have included those patches also in this series.

twl4030-usb and omap-usb2 have also been adapted to this framework.

These patches are also available @
