large change that introduces runtime PM support to the clk framework. Now we
 properly call runtime PM operations on the device providing a clk when the clk
 is in use. This helps on SoCs where the clks provided by a device need
 something to be powered on before using the clks, like power domains or
 regulators. It also helps power those things down when clks aren't in use. The
 other core change is a devm API addition for clk providers so we can get rid of
 a bunch of clk driver remove functions that are just doing
 of_clk_del_provider().
 
 Outside of the core, we have the usual addition of clk drivers and smattering
 of non-critical fixes to existing drivers. The biggest diff is support for
 Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch
 of data.
 
 By the way, we're trying something new here where we build the tree up with
 topic branches. We plan to work this into our workflow so that we don't step
 on each other's toes, and so the fixes branch can be merged on an as-needed
 basis.
 
 Core:
  - Runtime PM support for clk providers
  - devm API for of_clk_add_hw_provider()
 
 New Drivers:
  - Mediatek MT2712 and MT7622
  - Renesas R-Car V3M SoC
 
 Updates:
  - Runtime PM support for Samsung exynos5433/exynos4412 providers
  - Removal of clkdev aliases on Samsung SoCs
  - Convert clk-gpio to use gpio descriptors
  - Various driver cleanups to match kernel coding style
  - Amlogic Video Processing Unit VPU and VAPB clks
  - Sigma-delta modulation for Allwinner audio PLLs
  - Allwinner A83t Display clks
  - Support for the second display unit clock on Renesas RZ/G1E
  - Suspend/resume support for Renesas R-Car Gen3 CPG/MSSR
  - New clock ids for Rockchip rk3188 and rk3368 SoCs
  - Various 'const' markings on clk_ops structures
  - RPM clk support on Qualcomm MSM8996/MSM8660 SoCs
