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

Pull clk updates from Stephen Boyd:
 "Sort of on the quieter side this time, which is probably due more to
  me not catching up as quickly on patch review than anything else.
  Overall it seems normal though, a few small changes to the core,
  mostly small non-critical fixes here and there as well as driver
  updates for new and existing hardware support.

  The biggest things are the TI clk driver rework to lay the groundwork
  for clkctrl support in the next merge window and the AmLogic
  audio/graphics clk support.

  Core:
   - clk_possible_parents debugfs file so we know which parents a clk
     could possibly have
   - Fix to make clk rate change notifiers stop on the first failure
     instead of continuing

  New Drivers:
   - Mediatek MT6797 SoCs
   - hi655x PMIC clks
   - AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
   - Allwinner H5 SoCs and PRCM hardware

  Updates:
   - Nvidia Tegra T210 cleanups and non-critical fixes
   - TI OMAP cleanups in preparation for clkctrl support
   - trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
   - ZTE zx296718 SoC VGA clks
   - Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
   - IDT VersaClock 5P49V5935 support
   - Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3
     support"
