large change that introduces runtime PM support to the clk framework. Now we properly call runtime PM operations on the device providing a clk when the clk is in use. This helps on SoCs where the clks provided by a device need something to be powered on before using the clks, like power domains or regulators. It also helps power those things down when clks aren't in use. The other core change is a devm API addition for clk providers so we can get rid of a bunch of clk driver remove functions that are just doing of_clk_del_provider(). Outside of the core, we have the usual addition of clk drivers and smattering of non-critical fixes to existing drivers. The biggest diff is support for Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch of data. By the way, we're trying something new here where we build the tree up with topic branches. We plan to work this into our workflow so that we don't step on each other's toes, and so the fixes branch can be merged on an as-needed basis.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
