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

Pull clk updates from Stephen Boyd:
 "The large diff this time around is from the addition of a new clk
  driver for the TI Davinci family of SoCs. So far those clks have been
  supported with a custom implementation of the clk API in the arch port
  instead of in the CCF. With this driver merged we're one step closer
  to having a single clk API implementation.

  The other large diff is from the Amlogic clk driver that underwent
  some major surgery to use regmap. Beyond that, the biggest hitter is
  Samsung which needed some reworks to properly handle clk provider
  power domains and a bunch of PLL rate updates.

  The core framework was fairly quiet this round, just getting some
  cleanups and small fixes for some of the more esoteric features. And
  the usual set of driver non-critical fixes, cleanups, and minor
  additions are here as well.

  Core:
   - Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
   - debugfs ops macroized to shave some lines of boilerplate code
   - Always calculate the phase instead of caching it in clk_get_phase()
   - More __must_check on bulk clk APIs

  New Drivers:
   - TI's Davinci family of SoCs
   - Intel's Stratix10 SoC
   - stm32mp157 SoC
   - Allwinner H6 CCU
   - Silicon Labs SI544 clock generator chip
   - Renesas R-Car M3-N and V3H SoCs
   - i.MX6SLL SoCs

  Removed Drivers:
   - ST-Ericsson AB8540/9540

  Updates:
   - Mediatek MT2701 and MT7622 audsys support and MT2712 updates
   - STM32F469 DSI and STM32F769 sdmmc2 support
   - GPIO clks can sleep now
   - Spreadtrum SC9860 RTC clks
   - Nvidia Tegra MBIST workarounds and various minor fixes
   - Rockchip phase handling fixes and a memory leak plugged
   - Renesas drivers switch to readl/writel from clk_readl/clk_writel
   - Renesas gained CPU (Z/Z2) and watchdog support
   - Rockchip rk3328 display clks and rk3399 1.6GHz PLL support
   - Qualcomm PM8921 PMIC XO buffers
   - Amlogic migrates to regmap APIs
   - TI Keystone clk latching support
   - Allwinner H3 and H5 video clk fixes
   - Broadcom BCM2835 PLLs needed another bit to enable
   - i.MX6SX CKO mux fix and i.MX7D Video PLL divider fix
   - i.MX6UL/ULL epdc_podf support
   - Hi3798CV200 COMBPHY0 and USB2_OTG_UTMI and phase support for eMMC"
