This merge window we have one small clk provider API in the core framework and 

then a bunch of driver updates and a handful of new drivers. In terms of
 diffstat the Qualcomm and Amlogic drivers are high up there because of all the
 clk data introcued by new drivers. The Nvidia Tegra driver had a lot of work
 done this cycle too to support suspend/resume and memory controllers. And the
 OMAP clk driver got proper clk and reset handling in place.
 
 Rounding out the patches are various updates to remove unused data, mark things
 static, correct incorrect data in drivers, etc. All the little things that
 improve drivers and maintain code health. I will point out that there's a patch
 in here for the GPIO clk driver, that almost nobody uses, which changes
 behavior and causes clk_set_rate() to try to change the GPIO gate clk's parent.
 Other than that things are fairly well SoC specific here.
 
 Core:
  - Add a clk provider API to get current parent index
  - Plug a memory leak in clk_unregister() path
 
 New Drivers:
  - CGU in Ingenix X1000
  - Bitmain BM1880 clks
  - Qualcomm MSM8998 GPU clk controllers
  - Qualcomm SC7180 GCC and RPMH clk controllers

  - Add support for the Renesas RZ/G2N (r8a774b1) SoC
  - Add Tegra20/30 External Memory Clock (EMC) support
 
 Updates:
  - Make gpio gate clks propagate rate setting up to parent
  - Prepare Armada 3700 for suspend to RAM by moving PCIe suspend/resume priority
  - Drop unused variables, enums, etc. in various clk drivers
  - Convert various drivers to use devm_platform_ioremap_resource()
  - Use struct_size() some more in various clk drivers
  - Improve Rockchip px30 clk tree
  - Add suspend/resume support to Tegra210 clk driver
  - Reimplement SOR clks on earlier Tegra SoCs, helping HDMI and DP
  - Allwinner DT exports and H6 clk tree fixes
  - Proper clk and reset handling for OMAP SoCs
  - Revamped TI divider clk to clamp max divider
  - Make 1443X/1416X PLL clock structure common for reusing among i.MX8 SoCs
  - Drop IMX7ULP_CLK_MIPI_PLL clock, it shouldn't be used
  - Add VIDEO2_PLL clock for imx8mq
  - Add missing gate clock for pll1/2 fixed dividers on i.MX8 SoCs
  - Add sm1 support in the Amlogic audio clock controller
  - Switch some clocks on R-Car Gen2/3 to .determine_rate()
  - Remove Renesas R-Car Gen2 legacy DT clock support
  - Improve arithmetic divisions on Renesas R-Car Gen2 and Gen3

* Renesas R-Car Gen2 Clock Pulse Generator (CPG)
The CPG generates core clocks for the R-Car Gen2 SoCs. It includes three PLLs
and several fixed ratio dividers.
The CPG also provides a Clock Domain for SoC devices, in combination with the
CPG Module Stop (MSTP) Clocks.
Required Properties:
- compatible: Must be one of
- "renesas,r8a7790-cpg-clocks" for the r8a7790 CPG
- "renesas,r8a7791-cpg-clocks" for the r8a7791 CPG
- "renesas,r8a7792-cpg-clocks" for the r8a7792 CPG
- "renesas,r8a7793-cpg-clocks" for the r8a7793 CPG
- "renesas,r8a7794-cpg-clocks" for the r8a7794 CPG
and "renesas,rcar-gen2-cpg-clocks" as a fallback.
- reg: Base address and length of the memory resource used by the CPG
- clocks: References to the parent clocks: first to the EXTAL clock, second
to the USB_EXTAL clock
- #clock-cells: Must be 1
- clock-output-names: The names of the clocks. Supported clocks are "main",
"pll0", "pll1", "pll3", "lb", "qspi", "sdh", "sd0", "sd1", "z", "rcan", and
"adsp"
- #power-domain-cells: Must be 0
SoC devices that are part of the CPG/MSTP Clock Domain and can be power-managed
through an MSTP clock should refer to the CPG device node in their
"power-domains" property, as documented by the generic PM domain bindings in
Documentation/devicetree/bindings/power/power_domain.txt.
Examples
--------
- CPG device node:
cpg_clocks: cpg_clocks@e6150000 {
compatible = "renesas,r8a7790-cpg-clocks",
"renesas,rcar-gen2-cpg-clocks";

"lb", "qspi", "sdh", "sd0", "sd1", "z",
"rcan", "adsp";
#power-domain-cells = <0>;
};
- CPG/MSTP Clock Domain member device node:
thermal@e61f0000 {
compatible = "renesas,thermal-r8a7790", "renesas,rcar-thermal";
reg = <0 0xe61f0000 0 0x14>, <0 0xe61f0100 0 0x38>;

Enable backward compatibility with old device trees describing a
hierarchical representation of the various CPG and MSTP clocks.
Say Y if you want your kernel to work with old DTBs.
It is safe to say N if you use the DTS that is supplied with the
current kernel source tree.
