* Samsung Exynos5440 Clock Controller
The Exynos5440 clock controller generates and supplies clock to various
controllers within the Exynos5440 SoC.
Required Properties:
- compatible: should be "samsung,exynos5440-clock".
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
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
dt-bindings/clock/exynos5440.h header and can be used in device
tree sources.
Example: An example of a clock controller node is listed below.
clock: clock-controller@10010000 {
compatible = "samsung,exynos5440-clock";
reg = <0x160000 0x10000>;
#clock-cells = <1>;
};
Exynos5440 cpufreq driver
-------------------
Exynos5440 SoC cpufreq driver for CPU frequency scaling.
Required properties:
- interrupts: Interrupt to know the completion of cpu frequency change.
- operating-points: Table of frequencies and voltage CPU could be transitioned into,
in the decreasing order. Frequency should be in KHz units and voltage
should be in microvolts.
Optional properties:
- clock-latency: Clock monitor latency in microsecond.
All the required listed above must be defined under node cpufreq.
Example:
--------
cpufreq@160000 {
compatible = "samsung,exynos5440-cpufreq";
reg = <0x160000 0x1000>;
interrupts = <0 57 0>;

clock-latency = <100000>;

Qualcomm AOSS Reset Controller
======================================
This binding describes a reset-controller found on AOSS-CC (always on subsystem)
for Qualcomm SDM845 SoCs.
Required properties:
- compatible:
Usage: required
Value type: <string>
Definition: must be:
"qcom,sdm845-aoss-cc"
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: must specify the base address and size of the register
space.
- #reset-cells:
Usage: required
Value type: <uint>
Definition: must be 1; cell entry represents the reset index.
Example:
aoss_reset: reset-controller@c2a0000 {
compatible = "qcom,sdm845-aoss-cc";
reg = <0xc2a0000 0x31000>;
#reset-cells = <1>;
};
Specifying reset lines connected to IP modules
==============================================
Device nodes that need access to reset lines should
specify them as a reset phandle in their corresponding node as
specified in reset.txt.
For list of all valid reset indicies see
<dt-bindings/reset/qcom,sdm845-aoss.h>
Example:
