Pull clk updates from Stephen Boyd:
 "Here's a collection of largely clk driver updates. The usual suspects
  are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and Rockchip,
  but it feels pretty light on commits.

  There's only one real commit to the framework core and that's to
  consolidate code. Otherwise the diffstat is dominated by many Qualcomm
  clk driver patches that modernize the driver for the proper way of
  speciying clk parents. That's shifting data around, which could subtly
  break things so I'll be on the lookout for fixes.

  New Drivers:
   - Proper clk driver for Mediatek MT7621 SoCs
   - Support for the clock controller on the new Rockchip rk3568

  Updates:
   - Simplify Zynq Kconfig dependencies
   - Use clk_hw pointers in socfpga driver
   - Cleanup parent data in qcom clk drivers
   - Some cleanups for rk3399 modularization
   - Fix reparenting of i.MX UART clocks by initializing only the ones
     associated to stdout
   - Correct the PCIE clocks for i.MX8MP and i.MX8MQ
   - Make i.MX LPCG and SCU clocks return on registering failure
   - Kernel doc fixes
   - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N
   - Add timer (TMU) clocks on Renesas R-Car H3 ES1.0
   - Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on
     Renesas R-Car V3U
   - Sigma-delta modulation on Allwinner V3s audio PLL"
