The core framework got some nice improvements this time around. We gained the 

ability to get struct clk pointers from a struct clk_hw so that clk providers
 can consume the clks they provide, if they need to do something like that. This
 has been a long missing part of the clk provider API that will help us move
 away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are
 added for the clk_set_rate() "range" functions, similar to the tracepoints we
 already have for clk_set_rate() and we added a column to debugfs to help
 developers understand the hardware enable state of clks in case firmware or
 bootloader state is different than what is expected. Overall the core changes
 are mostly improving the clk driver writing experience.
 
 At the driver level, we have the usual collection of driver updates and new
 drivers for new SoCs. This time around the Qualcomm folks introduced a good
 handful of clk drivers for various parts of three or four SoCs. The SiFive
 folks added a new clk driver for their FU740 SoCs, coming in second on the
 diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that
 for various new features. One last thing to note in the driver area is that the
 i.MX driver has gained a new binding to support SCU clks after being on the
 list for many months. It uses a two cell binding which is sort of rare in clk
 DT bindings. Beyond that we have the usual set of driver fixes and tweaks that
 come from more testing and finding out that some configuration was wrong or
 that a driver could support being built as a module.
 
 Core:
  - Add some trace points for clk_set_rate() "range" functions
  - Add hardware enable information to clk_summary debugfs
  - Replace clk-provider.h with of_clk.h when possible
  - Add devm variant of clk_notifier_register()
  - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw
 
 New Drivers:
  - Bindings for Canaan K210 SoC clks
  - Support for SiFive FU740 PRCI
  - Camera clks on Qualcomm SC7180 SoCs
  - GCC and RPMh clks on Qualcomm SDX55 SoCs
  - RPMh clks on Qualcomm SM8350 SoCs
  - LPASS clks on Qualcomm SM8250 SoCs
 
 Updates:
  - DVFS support for AT91 clk driver
  - Update git repo branch for Renesas clock drivers
  - Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U
  - Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E
  - Stop using __raw_*() I/O accessors in Renesas clk drivers
  - One more conversion of DT bindings to json-schema
  - Make i.MX clk-gate2 driver more flexible

Binding for the axi-clkgen clock generator
This binding uses the common clock binding[1].
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible : shall be "adi,axi-clkgen-1.00.a" or "adi,axi-clkgen-2.00.a".
- #clock-cells : from common clock binding; Should always be set to 0.
- reg : Address and length of the axi-clkgen register set.
- clocks : Phandle and clock specifier for the parent clock(s). This must
either reference one clock if only the first clock input is connected or two
if both clock inputs are connected. For the later case the clock connected
to the first input must be specified first.
Optional properties:
- clock-output-names : From common clock binding.
Example:

compatible = "adi,axi-clkgen";
#clock-cells = <0>;

* Renesas R-Car USB 2.0 clock selector
This file provides information on what the device node for the R-Car USB 2.0
clock selector.
If you connect an external clock to the USB_EXTAL pin only, you should set
the clock rate to "usb_extal" node only.
If you connect an oscillator to both the USB_XTAL and USB_EXTAL, this module
is not needed because this is default setting. (Of course, you can set the
clock rates to both "usb_extal" and "usb_xtal" nodes.
Case 1: An external clock connects to R-Car SoC
+----------+ +--- R-Car ---------------------+
|External |---|USB_EXTAL ---> all usb channels|
|clock | |USB_XTAL |
+----------+ +-------------------------------+
In this case, we need this driver with "usb_extal" clock.
Case 2: An oscillator connects to R-Car SoC
+----------+ +--- R-Car ---------------------+
|Oscillator|---|USB_EXTAL -+-> all usb channels|
| |---|USB_XTAL --+ |
+----------+ +-------------------------------+
In this case, we don't need this selector.
Required properties:
- compatible: "renesas,r8a7795-rcar-usb2-clock-sel" if the device is a part of
an R8A7795 SoC.
"renesas,r8a7796-rcar-usb2-clock-sel" if the device if a part of
an R8A77960 SoC.
"renesas,r8a77961-rcar-usb2-clock-sel" if the device if a part of
an R8A77961 SoC.
"renesas,rcar-gen3-usb2-clock-sel" for a generic R-Car Gen3
compatible device.
When compatible with the generic version, nodes must list the
SoC-specific version corresponding to the platform first
followed by the generic version.
- reg: offset and length of the USB 2.0 clock selector register block.
- clocks: A list of phandles and specifier pairs.
- clock-names: Name of the clocks.
- The functional clock of USB 2.0 host side must be "ehci_ohci"
- The functional clock of HS-USB side must be "hs-usb-if"
- The USB_EXTAL clock pin must be "usb_extal"
- The USB_XTAL clock pin must be "usb_xtal"
- #clock-cells: Must be 0
- power-domains: A phandle and symbolic PM domain specifier.
See power/renesas,rcar-sysc.yaml.
- resets: A list of phandles and specifier pairs.

description: |
If you connect an external clock to the USB_EXTAL pin only, you should set
the clock rate to "usb_extal" node only.
If you connect an oscillator to both the USB_XTAL and USB_EXTAL, this module
is not needed because this is default setting. (Of course, you can set the
clock rates to both "usb_extal" and "usb_xtal" nodes.
Case 1: An external clock connects to R-Car SoC
+----------+ +--- R-Car ---------------------+
|External |---|USB_EXTAL ---> all usb channels|
|clock | |USB_XTAL |
+----------+ +-------------------------------+
In this case, we need this driver with "usb_extal" clock.
Case 2: An oscillator connects to R-Car SoC
+----------+ +--- R-Car ---------------------+
|Oscillator|---|USB_EXTAL -+-> all usb channels|
| |---|USB_XTAL --+ |
+----------+ +-------------------------------+
In this case, we don't need this selector.

description:
On the FU740 family of SoCs, most system-wide clock and reset integration
is via the PRCI IP block.
The clock consumer should specify the desired clock via the clock ID
macros defined in include/dt-bindings/clock/sifive-fu740-prci.h.
These macros begin with PRCI_CLK_.
The hfclk and rtcclk nodes are required, and represent physical
crystals or resonators located on the PCB. These nodes should be present
underneath /, rather than /soc.
