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

Pull clk updates from Stephen Boyd:
 "The usual collection of new drivers, non-critical fixes, and updates
  to existing clk drivers. The bulk of the work is on Allwinner and
  Rockchip SoCs, but there's also an Intel Atom driver in here too.

  New Drivers:
   - Tegra BPMP firmware
   - Hisilicon hi3660 SoCs
   - Rockchip rk3328 SoCs
   - Intel Atom PMC
   - STM32F746
   - IDT VersaClock 5P49V5923 and 5P49V5933
   - Marvell mv98dx3236 SoCs
   - Allwinner V3s SoCs

  Removed Drivers:
   - Samsung Exynos4415 SoCs

  Updates:
   - Migrate ABx500 to OF
   - Qualcomm IPQ4019 CPU clks and general PLL support
   - Qualcomm MSM8974 RPM
   - Rockchip non-critical fixes and clk id additions
   - Samsung Exynos4412 CPUs
   - Socionext UniPhier NAND and eMMC support
   - ZTE zx296718 i2s and other audio clks
   - Renesas CAN and MSIOF clks for R-Car M3-W
   - Renesas resets for R-Car Gen2 and Gen3 and RZ/G1
   - TI CDCE913, CDCE937, and CDCE949 clk generators
   - Marvell Armada ap806 CPU frequencies
   - STM32F4* I2S/SAI support
   - Broadcom BCM2835 DSI support
   - Allwinner sun5i and A80 conversion to new style clk bindings"
