This time we have a good set of changes to the core framework that do some

general cleanups, but nothing too major. The majority of the diff goes to
 two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for
 Actions Semi so it takes up some lines to add all the different types, and
 the Qualcomm diff is there because we add support for two SoCs and it's quite
 a bit of data.
 
 Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And
 then the long tail of driver updates for various fixes and stuff follows
 after that.
 
 Core:
  - debugfs cleanups removing error checking and an unused provider API
  - Removal of a clk init typedef that isn't used
  - Usage of match_string() to simplify parent string name matching
  - OF clk helpers moved to their own file (linux/of_clk.h)
  - Make clk warnings more readable across kernel versions
 
 New Drivers:
  - Qualcomm SDM845 GCC and Video clk controllers
  - Qualcomm MSM8998 GCC
  - Actions Semi S900 SoC support
  - Nuvoton npcm750 microcontroller clks
  - Amlogic axg AO clock controller
 
 Removed Drivers:
  - Deprecated Rockchip clk-gate driver
 
 Updates:
  - debugfs functions stopped checking return values
  - Support for the MSIOF module clocks on Rensas R-Car M3-N
  - Support for the new Rensas RZ/G1C and R-Car E3 SoCs
  - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs
  - Berlin and Amlogic SPDX tagging
  - Usage of of_clk_get_parent_count() in more places
  - Proper implementation of the CDEV1/2 clocks on Tegra20
  - Allwinner H6 PRCM clock support and R40 EMAC support
  - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet
  - Round closest support for meson's mpll driver
  - Support for meson8b nand clocks and gxbb video decoder clocks
  - Mediatek mali clks
  - STM32MP1 fixes
  - Uniphier LD11/LD20 stream demux system clock

+MediaTek g3dsys controller
+============================
+
+The MediaTek g3dsys controller provides various clocks and reset controller to
+the GPU.
+
+Required Properties:
+
+- compatible: Should be:
+	- "mediatek,mt2701-g3dsys", "syscon":
+		for MT2701 SoC
+	- "mediatek,mt7623-g3dsys", "mediatek,mt2701-g3dsys", "syscon":

+- #clock-cells: Must be 1
+- #reset-cells: Must be 1
+
+The g3dsys controller uses the common clk binding from
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+The available clocks are defined in dt-bindings/clock/mt*-clk.h.
+
+Example:
+
+g3dsys: clock-controller@13000000 {
+	compatible = "mediatek,mt7623-g3dsys",
+		     "mediatek,mt2701-g3dsys",

+* Actions S900 Clock Management Unit (CMU)
+
+The Actions S900 clock management unit generates and supplies clock to various
+controllers within the SoC. The clock binding described here is applicable to
+S900 SoC.
+
+Required Properties:
+
+- compatible: should be "actions,s900-cmu"
+- reg: physical base address of the controller and length of memory mapped
+  region.
+- clocks: Reference to the parent clocks ("hosc", "losc")
+- #clock-cells: should be 1.
+
+Each clock is assigned an identifier, and client nodes can use this identifier
+to specify the clock which they consume.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/actions,s900-cmu.h header and can be used in device
+tree sources.
+
+External clocks:
+
+The hosc clock used as input for the plls is generated outside the SoC. It is
+expected that it is defined using standard clock bindings as "hosc".
+
+Actions S900 CMU also requires one more clock:
+ - "losc" - internal low frequency oscillator
+
+Example: Clock Management Unit node:
+
+        cmu: clock-controller@e0160000 {
+                compatible = "actions,s900-cmu";

+                #clock-cells = <1>;
+        };
+
+Example: UART controller node that consumes clock generated by the clock
+management unit:

+* Nuvoton NPCM7XX Clock Controller
+
+Nuvoton Poleg BMC NPCM7XX contains an integrated clock controller, which
+generates and supplies clocks to all modules within the BMC.
+
+External clocks:
+
+There are six fixed clocks that are generated outside the BMC. All clocks are of
+a known fixed value that cannot be changed. clk_refclk, clk_mcbypck and
+clk_sysbypck are inputs to the clock controller.
+clk_rg1refck, clk_rg2refck and clk_xin are external clocks suppling the
+network. They are set on the device tree, but not used by the clock module. The
+network devices use them directly.
+Example can be found below.
+
+All available clocks are defined as preprocessor macros in:
+dt-bindings/clock/nuvoton,npcm7xx-clock.h
+and can be reused as DT sources.
+
+Required Properties of clock controller:

+	- compatible: "nuvoton,npcm750-clk" : for clock controller of Nuvoton
+		  Poleg BMC NPCM750

-structure a matter of taste, as either all gates can be put into
-one gate clock spanning all registers or they can be divided into
-the 10 individual gates containing 16 clocks each.
-The code supports both approaches.
-
-Required properties:
-- compatible : "rockchip,rk2928-gate-clk"
-- reg : shall be the control register address(es) for the clock.
-- #clock-cells : from common clock binding; shall be set to 1
-- clock-output-names : the corresponding gate names that the clock controls
-- clocks : should contain the parent clock for each individual gate,
-  therefore the number of clocks elements should match the number of
-  clock-output-names
-
-Example using multiple gate clocks:
-
-		clk_gates0: gate-clk@200000d0 {
-			compatible = "rockchip,rk2928-gate-clk";
