Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "The clk changes for this release cycle are mostly dominated by new
  device support in terms of LoC, but there has been some cleanup in the
  core as well as the usual minor clk additions to various drivers.

  Core:
   - parent tracking has been simplified
   - CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
   - of_clk_init() doesn't consider disabled DT nodes anymore
   - clk_unregister() had an error path bug squashed
   - of_clk_get_parent_count() has been fixed to only return unsigned ints
   - HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone

  New Drivers:
   - NXP LPC18xx creg
   - QCOM IPQ4019 GCC
   - TI dm814x ADPLL
   - i.MX6QP

  Updates:
   - Cyngus audio clks found on Broadcom iProc devices
   - Non-critical fixes for BCM2385 PLLs
   - Samsung exynos5433 updates for clk id errors, HDMI support,
     suspend/resume simplifications
   - USB, CAN, LVDS, and FCP clks on shmobile devices
   - sunxi got support for more clks on new SoCs and went through a
     minor refactoring/rewrite to use a simpler factor clk construct
   - rockchip added some more clk ids and added suport for fraction
     dividers
   - QCOM GDSCs in msm8996
   - A new devm helper to make adding custom actions simpler (acked by Greg)"
