The clk framework and driver changes for 4.5 look pretty typical. The
bulk of the changes are to clk controller drivers, though some improvements to the core and some re-usable blocks/templates also received some love. In this past cycle the clk maintainers developed a good workflow for handling the common case of patch submissions containing a new drivers, new shared Device Tree header and a new Device Tree binding description. This requires coordination with the Device Tree maintainers and with the architecture maintainers (typically the arm-soc tree in our case). This explains the increase in changes to include/dt-bindings/... and to Documentation/devicetree/bindings/clock/... coming from the clk tree. The same commits can be expected to come through those trees on occasion, through the use of shared, immutable branches. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJWmVD1AAoJEKI6nJvDJaTUWqAQAJRqH+iKSnLyuVek6USYPXdp ZOW1JHIySCUF/ci3fvv9vbIuW/w4Uc9FdRdAfIIaWO32bpk4ljtEogVasvavL/54 geN+0YERZpth+PL/wk+g+Dons/8BgN9AL+0ToaVVh2MsRE903jWpe+l0qWCl+SUn DQF+yB9F4QcVT7gb+KI0B6hr6lv5Mu/t9Ffq3DrK2UG71IEbrv953pVo19foZqbf FgMgduERMHvaM/R6p5xfXxIESbjE+QNMnykEo6bWcHF2wfQrIiYlW1khtnsigNus kze2mYWjG77KGkrOex5kwjuBDPfiaGAstk3jcRCCMB7nRmuFcJgryF8003CD3QvW +cY+ZBSkyXXtL/nrkefebAplQjsvum7dJ+W6hxA32B772jFL8s8ee5rGda0ibw8N nFQRopVcNPoR52tjmSEOxm7Z9vqoDj5qManDdZe62kr6bCFId97E6SzeGgeyDuBQ V7tkss9klHMhx29V37wkyl+A/pWXO+CsGzHLEivH8/L1CysMK1WGhyHJJ2/JTDTR n3z1EYdg67PbHpfhboscuLP+sHcrAefOCe2la4wKxwqd4DGw6J8RhhVZml6XnfQ3 I4yLri8Pguol49G1ac1U87ylebKsXhWR5CRHVas1BFHrt0FGULHnl0ZOLzOu4GRZ h8/nd9ZODLFhB1w7fL1B =nkGr -----END PGP SIGNATURE----- Merge tag 'clk-for-linus-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk framework updates from Michael Turquette: "The clk framework and driver changes for 4.5 look pretty typical.

This binding uses the common clock binding:

Documentation/devicetree/bindings/clock/clock-bindings.txt

The auxiliary peripherals (UART, SPI1, and SPI2) have a small register

area controlling clock gating to the peripherals, and providing an IRQ

status register.

found in include/dt-bindings/clock/bcm2835-aux.h

NVIDIA Tegra210 Clock And Reset Controller
|

|

This binding uses the common clock binding:
|

Documentation/devicetree/bindings/clock/clock-bindings.txt
|
||||
|
||||
The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
|
||||
for muxing and gating Tegra's clocks, and setting their rates.
|
||||
|
||||
Required properties :
|
||||
- compatible : Should be "nvidia,tegra210-car"
|
||||
- reg : Should contain CAR registers location and length
|
||||
- clocks : Should contain phandle and clock specifiers for two clocks:
|
||||
the 32 KHz "32k_in".
|
||||
- #clock-cells : Should be 1.
|
||||
In clock consumers, this cell represents the clock ID exposed by the
|
||||
CAR. The assignments may be found in header file
|
||||
<dt-bindings/clock/tegra210-car.h>.
|
||||
- #reset-cells : Should be 1.
|
||||
In clock consumers, this cell represents the bit number in the CAR's
|
||||
array of CLK_RST_CONTROLLER_RST_DEVICES_* registers.

|
||||
|
||||

* Rockchip RK3036 Clock and Reset Unit
|

|

The RK3036 clock controller generates and supplies clock to various

Required 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/rk3036-cru.h headers and can be

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:

* Sigma Designs Tango4 Clock Generator
|
||||
|
||||
The Tango4 clock generator outputs cpu_clk and sys_clk (the latter is used
|
||||
for RAM and various peripheral devices). The clock binding described here
|
||||
is applicable to all Tango4 SoCs.
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible: should be "sigma,tango4-clkgen".
|
||||
- reg: physical base address of the device and length of memory mapped region.
|
||||
- clocks: phandle of the input clock (crystal oscillator).
|
||||
- clock-output-names: should be "cpuclk" and "sysclk".
|
||||
- #clock-cells: should be set to 1.
|
||||
|
||||
Example:
|
||||
|
||||
clkgen: clkgen@10000 {
|
||||
compatible = "sigma,tango4-clkgen";
|
||||
reg = <0x10000 0x40>;
|
||||
clocks = <&xtal>;
|
||||
clock-output-names = "cpuclk", "sysclk";
|
||||
#clock-cells = <1>;
|
||||
};
