Pull clk updates from Stephen Boyd: "Here's the clk changes for the merge window which is dominated in the diffstat by Qualcomm churning out new SoCs that need clk drivers. Looking beyond the sheer amount of lines of mostly data there we have a clk nexus DT binding change in the core clk framework and a driver core patch to add a subsys driver macro. The clock nexus support is useful for devices that map clks internally or for connectors on a board that route clock signals to another board. I suspect the use of this will expand in the future, so we have unit tests to make sure it doesn't break. The driver core change adds subsys_driver() and subsys_platform_driver() so we can register early drivers without open-coding that all (module_platform_driver() is at device initcall level so it isn't be used). Beyond the core framework bits we have lots of changes all over the tree to initialize 'struct clk_init_data'. The potential risk here is that someone forgets to initialize all the members of that structure and either the clk flags cause weird behavior later on or the parents are pointing at junk and the clk is orphaned forever. The patches just initialize the thing with zeroes to be safe. Longer term we should probably move this struct out of 'struct clk_hw' and pass it during clk registration time. That's a much bigger change and would require restructuring entire drivers that rely on the pointer being there. Finally, we have the usual fixes like calculation updates for dividers, handling error paths during clk registration, or fixing clk data now that drivers are using them. Those patches are dwarfed by the amount of new SoC support and only affect those SoCs and the consumers of those clks. Overall I'm more concerned the clk_init_data patches are going to expose some latent bugs that we didn't notice before because something was relying on clks being orphaned and now they're not.
