PHY Framework for 3.12 merge window

Hi Greg,

Here's the pull request for the PHY Framework which I've been working on for a while.

I've applied these patches on the current linux mainline HEAD (which has one commit after 3.11-rc1 is tagged).

Even before this framework is merged, quite a few people started using it. I've queued those patches along with the PHY framework as well.

I'm also planning to maintain this framework henceforth and will be sending pull requests for anything related to this framework or users of this framework.

Let me know if you want any changes on this pull request

Thanks
Kishon

video: exynos_dp: Use the generic PHY driver (2013-07-16 14:37:04 +0530)

----------------------------------------------------------------
PHY: patches for 3.12 merge window

We're introducing a new kernel wide generic PHY framework.

This 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.

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 for better code maintainability.

There are already quite a few users for this framework.
Samsung Exynos SoC Display Port PHY and MIPI PHY are some of the early users of this framework in addition to OMAP-USB2 PHY and TWL4030-USB.

I'm sorry, but I can't pull from a non-kernel.org account. And, why is
this a pull request at all? There aren't many patches in this series,
I can take them just fine through email. I only do pull requests from a _very_ limited number of people whom I have been working with for a long time, everyone else I handle just fine with email.

Also, why me for this? Should it go through my "char/misc" tree? Do
you have sign-offs for the subsystems that you touch? Will you be moving more phy code from the different subsystems (like all the USB phy code), into here as well? Or is this just for new devices?

thanks,
