Pull clk updates from Stephen Boyd:
 "This time we've got one core change to introduce a bulk clk_get API,
  some new clk drivers and updates for old ones. The diff is pretty
  spread out across a handful of different SoC clk drivers for Broadcom,
  TI, Qualcomm, Renesas, Rockchip, Samsung, and Allwinner, mostly due to
  the introduction of new drivers.

  Core:
   - New clk bulk get APIs
   - Clk divider APIs gained the ability to consider a different parent
     than the current one

  New Drivers:
   - Renesas r8a779{0,1,2,4} CPG/MSSR
   - TI Keystone SCI firmware controlled clks and OMAP4 clkctrl
   - Qualcomm IPQ8074 SoCs
   - Cortina Systems Gemini (SL3516/CS3516)
   - Rockchip rk3128 SoCs
   - Allwinner A83T clk control units
   - Broadcom Stingray SoCs
   - CPU clks for Mediatek MT8173/MT2701/MT7623 SoCs

  Removed Drivers:
   - Old non-DT version of the Realview clk driver

  Updates:
   - Renesas Kconfig/Makefile cleanups
   - Amlogic CEC EE clk support
   - Improved Armada 7K/8K cp110 clk support
   - Rockchip clk id exposing, critical clk markings
   - Samsung converted to clk_hw registration APIs
   - Fixes for Samsung exynos5420 audio clks
   - USB2 clks for Hisilicon hi3798cv200 SoC and video/camera clks for
     hi3660"
