The new and exciting feature this time around is in the clk core. 

We've added duty cycle support to the clk API so that clk signal
 duty cycle ratios can be adjusted while taking into account things
 like clk dividers and clk tree hierarchy. So far only one SoC has
 implemented support for this, but I expect there will be more to
 come in the future.
 
 Outside of the core, we have the usual pile of clk driver updates
 and additions. The Amlogic meson driver got the most lines in the
 diffstat this time around because it added support for a whole bunch
 of hardware and duty cycle configuration. After that the Rockchip PX30,
 Qualcomm SDM845, and Renesas SoC drivers fill in a majority of the diff.
 We're left with the collection of non-critical fixes after that. Overall
 it looks pretty quiet this time.

* Rockchip PX30 Clock and Reset Unit
The PX30 clock controller generates and supplies clock to various
controllers within the SoC and also implements a reset controller for SoC
peripherals.
Required Properties:
- compatible: PMU for CRU should be "rockchip,px30-pmu-cru"
- compatible: CRU should be "rockchip,px30-cru"
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
- #reset-cells: should be 1.
Optional Properties:
- rockchip,grf: phandle to the syscon managing the "general register files"
If missing, pll rates are not changeable, due to the missing pll lock status.
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 the dt-bindings/clock/px30-cru.h headers and can be
used in device tree sources. Similar macros exist for the reset sources in
these files.
External clocks:
There are several clocks that are generated outside the SoC. It is expected
that they are defined using standard clock bindings with following
clock-output-names:
- "xin24m" - crystal input - required,
- "xin32k" - rtc clock - optional,
- "i2sx_clkin" - external I2S clock - optional,
- "gmac_clkin" - external GMAC clock - optional
Example: Clock controller node:
pmucru: clock-controller@ff2bc000 {
compatible = "rockchip,px30-pmucru";
reg = <0x0 0xff2bc000 0x0 0x1000>;
#clock-cells = <1>;
#reset-cells = <1>;
};
cru: clock-controller@ff2b0000 {
compatible = "rockchip,px30-cru";
reg = <0x0 0xff2b0000 0x0 0x1000>;
rockchip,grf = <&grf>;
#clock-cells = <1>;
#reset-cells = <1>;
};
Example: UART controller node that consumes the clock generated by the clock
controller:
uart0: serial@ff030000 {
compatible = "rockchip,px30-uart", "snps,dw-apb-uart";
reg = <0x0 0xff030000 0x0 0x100>;
