Here's the main clk pull request for this merge window. We have some
late breaking reports that a patch series to rework clk rate range support broke boot on some devices, so I've left that branch out of this PR. Hopefully we can get to that next week, or punt on it and let it bake another cycle. That means we don't really have any changes to the core framework this time around besides a few typo fixes. Instead this is all clk driver updates and fixes. The usual suspects are here (again), with Qualcomm dominating the diffstat. We look to have gained support for quite a few new Qualcomm SoCs and Dmitry worked on updating many of the existing Qualcomm drivers to use clk_parent_data. After that we have MediaTek drivers getting some much needed updates, in particular to support GPU DVFS. There are also quite a few Samsung clk driver patches, but that's mostly because there was a maintainer change and so last release we missed some of those patches. Overall things look normal, but I'm slowly reviewing core framework code nowadays and that shows given the rate range patches had to be yanked last minute. Let's hope this situation changes soon.

Binding for simple gpio gated clock.
|

|

This binding uses the common clock binding[1].
|

|

[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
|
||||
|

Required properties:
|

- compatible : shall be "gpio-gate-clock".
|
||||
- #clock-cells : from common clock binding; shall be set to 0.
|
||||
- enable-gpios : GPIO reference for enabling and disabling the clock.
|
||||
|
||||
Optional properties:
|
||||
- clocks: Maximum of one parent clock is supported.
|
||||
|
||||
Example:
|
||||
clock {
|
||||
compatible = "gpio-gate-clock";
|
||||
clocks = <&parentclk>;
|
||||
#clock-cells = <0>;

enable-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;

* Rockchip RK3126/RK3128 Clock and Reset Unit
|
||||
|
||||
The RK3126/RK3128 clock controller generates and supplies clock to various
|
||||
controllers within the SoC and also implements a reset controller for SoC
|
||||
peripherals.
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible: should be "rockchip,rk3126-cru" or "rockchip,rk3128-cru"
|
||||
"rockchip,rk3126-cru" - controller compatible with RK3126 SoC.
|
||||
"rockchip,rk3128-cru" - controller compatible with RK3128 SoC.
|
||||
- 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/rk3128-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,
|
||||
- "ext_i2s" - external I2S clock - optional,
|
||||
- "gmac_clkin" - external GMAC clock - optional
|
||||
|
||||
Example: Clock controller node:
|
||||
|
||||
cru: cru@20000000 {
|
||||
compatible = "rockchip,rk3128-cru";
|
||||
reg = <0x20000000 0x1000>;
|
||||
rockchip,grf = <&grf>;
|
||||
|
||||
#clock-cells = <1>;
|
||||
#reset-cells = <1>;
|
||||
};
|
||||
|
||||
Example: UART controller node that consumes the clock generated by the clock
|
||||
controller:
|
||||
|
||||
uart2: serial@20068000 {
|
||||
compatible = "rockchip,serial";
|
||||
reg = <0x20068000 0x100>;
|
||||
interrupts = <GIC_SPI 22 IRQ_TYPE_LEVEL_HIGH>;
|
||||
clock-frequency = <24000000>;
|
||||
clocks = <&cru SCLK_UART2>, <&cru PCLK_UART2>;
|
||||
clock-names = "sclk_uart", "pclk_uart";
|
||||
};
