The majority of the changes are driver updates and new device

support. The core framework is mostly unchanged this time
 around, with only a couple patches to expose a clk provider
 API and make getting clk parent names from DT more robust.
 
 Driver updates:
 
 - Support for clock controllers found on Broadcom Northstar
   SoCs and bcm2835 SoC
 
 - Support for Allwinner audio clocks
 
 - A few cleanup patches for Tegra drivers and support for the
   highest DFLL frequencies on Tegra124
 
 - Samsung exynos7 fixes and improvements
 
 - i.Mx SoC updates to add a few missing clocks and keep debug
   uart clocks on during kernel intialization
 
 - Some mediatek cleanups and support for more subsystem clocks
 
 - Support for msm8916 gpu/audio clocks and qcom's GDSC power domain
   controllers
 
 - A new driver for the Silabs si514 clock chip

Broadcom BCM2835 CPRMAN clocks
This binding uses the common clock binding:
Documentation/devicetree/bindings/clock/clock-bindings.txt
The CPRMAN clock controller generates clocks in the audio power domain
of the BCM2835. There is a level of PLLs deriving from an external
oscillator, a level of PLL dividers that produce channels off of the
few PLLs, and a level of mostly-generic clock generators sourcing from
the PLL channels. Most other hardware components source from the
clock generators, but a few (like the ARM or HDMI) will source from
the PLL dividers directly.
Required properties:
- compatible: Should be "brcm,bcm2835-cprman"
- #clock-cells: Should be <1>. The permitted clock-specifier values can be
found in include/dt-bindings/clock/bcm2835.h
- reg: Specifies base physical address and size of the registers
- clocks: The external oscillator clock phandle
Example:
clk_osc: clock@3 {
compatible = "fixed-clock";
reg = <3>;
#clock-cells = <0>;
clock-output-names = "osc";
clock-frequency = <19200000>;
};
clocks: cprman@7e101000 {

* Renesas Clock Pulse Generator / Module Standby and Software Reset
On Renesas ARM SoCs (SH/R-Mobile, R-Car, RZ), the CPG (Clock Pulse Generator)
and MSSR (Module Standby and Software Reset) blocks are intimately connected,
and share the same register block.
They provide the following functionalities:
- The CPG block generates various core clocks,
- The MSSR block provides two functions:
1. Module Standby, providing a Clock Domain to control the clock supply
to individual SoC devices,
2. Reset Control, to perform a software reset of individual SoC devices.
Required Properties:
- compatible: Must be one of:
- "renesas,r8a7795-cpg-mssr" for the r8a7795 SoC
- reg: Base address and length of the memory resource used by the CPG/MSSR
block
- clocks: References to external parent clocks, one entry for each entry in
clock-names
- clock-names: List of external parent clock names. Valid names are:
- "extal" (r8a7795)
- "extalr" (r8a7795)
- #clock-cells: Must be 2
- For CPG core clocks, the two clock specifier cells must be "CPG_CORE"
and a core clock reference, as defined in
<dt-bindings/clock/*-cpg-mssr.h>.
- For module clocks, the two clock specifier cells must be "CPG_MOD" and
a module number, as defined in the datasheet.
- #power-domain-cells: Must be 0
- SoC devices that are part of the CPG/MSSR Clock Domain and can be
power-managed through Module Standby 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: clock-controller@e6150000 {
compatible = "renesas,r8a7795-cpg-mssr";
reg = <0 0xe6150000 0 0x1000>;
