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

Pull clk updates from Stephen Boyd:
 "This time it looks like a quieter release cycle in the clk tree. I
  guess that's because of summer time holidays/vacations. The biggest
  change in the diffstat is in the Qualcomm clk driver, where they got
  support for CPUs and handful of SoCs. After that, the at91 driver got
  a major rewrite for newer DT bindings that should make things easier
  going forward and the TI code moved to a clockdomain based design.

  The long tail is mostly small driver updates for newer clks and some
  simpler SoC clock drivers such as the Hisilicon and imx support.

  In the core framework, we only have two small changes this time.

  One is a new clk API to get all clks for a device with the bulk clk
  APIs. This allows drivers that don't care about doing anything besides
  turning on all the clks to just clk_get() them all and turn them on.

  The other change is the beginning of a way to support save and restore
  of clk settings in the clk framework. TI is the only user right now,
  but we will want to expand upon this design in the future to support
  more save and restore of clk registers. At least this gets us started
  and works well enough for one SoC, but there's more work in the
  future.

  Core:
   - clk_bulk_get_all() API and friends to get all the clks for a device
   - Basic clk state save/restore hooks

  New Drivers:
   - Renesas RZ/A2 (R7S9210) SoC, including early clocks
   - Rensas RZ/G1N (R8A7744) and RZ/G2E (R8A774C0) SoCs
   - Rensas RZ/G2M (r8a774a1) SoC
   - Qualcomm Krait CPU clk support
   - Qualcomm QCS404 GCC support
   - Qualcomm SDM660 GCC support
   - Qualcomm SDM845 camera clock controller
   - Ingenic jz4725b CGU
   - Hisilicon 3670 SoC support
   - TI SCI clks on K3 SoCs
   - iMX6 MMDC clks
   - Reset Controller (RMU) support for Actions Semi Owl S900 and S700 SoCs

  Updates:
   - Rework at91 PMC clock driver for new DT bindings
   - Nvidia Tegra clk driver MBIST workaround fix
   - S2RAM support for Marvell mvebu periph clks
   - Use updated printk format for OF node names
   - Fix TI code to only search DT subnodes
   - Various static analysis finds
   - Tag various drivers with SPDX license tags
   - Support dynamic frequency switching (DFS) on qcom SDM845 GCC
   - Only use s2mps11 dt-binding defines instead of redefining them in the driver
   - Add some more missing clks to qcom MSM8996 GCC
   - Quad SPI clks on qcom SDM845
   - Add support for CMT timer clocks on R-Car V3H
   - Add support for SHDI and various timer clocks on R-Car V3M
   - Improve OSC and RCLK (watchdog) handling on R-Car Gen3 SoCs
   - Amlogic clk-pll driver improvements and updates
   - Amlogic axg audio controller system clocks
   - Register Amlogic meson8b clock controller early
   - Add support for SATA and Fine Display Processor (FDP) clocks on R-Car M3-N
   - Consolidation of system suspend related code in Exynos, S5P, S3C SoC clk drivers
   - Fixes for system suspend support on Exynos542x (Odroid boards) and Exynos5433 SoC
   - Remove obsoleted Exynos4212 ISP clock definitions
   - Migrated TI am3/4/5 and dra7 SoCs to clockdomain based design
   - TI RTC+DDR sleep mode support for clock save/restore
   - Allwinner A64 display engine support and fixes
   - Allwinner A83t display engine support and fixes"
