Linus Torvalds c0fa2373f8 The clk tree changes for 3.18 are dominated by clock drivers. Mostly
fixes and enhancements to existing drivers as well as new drivers. This
 tag contains a bit more arch code than I usually take due to some OMAP2+
 changes. Additionally it contains the restart notifier handlers which
 are merged as a dependency into several trees.
 
 The PXA changes are the only messy part. Due to having a stable tree I
 had to revert one patch and follow up with one more fix near the tip of
 this tag. Some dead code is introduced but it will soon become live code
 after 3.18-rc1 is released as the rest of the PXA family is converted
 over to the common clock framework.
 
 Another trend in this tag is that multiple vendors have started to push
 the complexity of changing their CPU frequency into the clock driver,
 whereas this used to be done in CPUfreq drivers.
 
 Changes to the clk core include a generic gpio-clock type and a
 clk_set_phase() function added to the top-level clk.h api. Due to some
 confusion on the fbdev mailing list the kernel boot parameters
 documentation was updated to further explain the clk_ignore_unused
 parameter, which is often required by users of the simplefb driver.
 Finally some fixes to the locking around the clock debugfs stuff was
 done to prevent deadlocks when interacting with other subsystems.
