This binding is a work-in-progress, and are based on some experimental
|
||||
work by benh[1].
|
||||
|
||||
Sources of clock signal can be represented by any node in the device
|
||||
tree. Those nodes are designated as clock providers. Clock consumer
|
||||
nodes use a phandle and clock specifier pair to connect clock provider
|
||||
outputs to clock inputs. Similar to the gpio specifiers, a clock
|
||||
specifier is an array of zero, one or more cells identifying the clock
|
||||
output on a device. The length of a clock specifier is defined by the
|
||||
value of a #clock-cells property in the clock provider node.
|
||||
|
||||
[1] https://patchwork.ozlabs.org/patch/31551/
|
||||
|
||||
==Clock providers==
|
||||
|
||||
Required properties:
|
||||
#clock-cells: Number of cells in a clock specifier; Typically 0 for nodes
|
||||
with a single clock output and 1 for nodes with multiple
|
||||
clock outputs.
|
||||
|
||||
Optional properties:
|
||||
clock-output-names: Recommended to be a list of strings of clock output signal
|
||||
names indexed by the first cell in the clock specifier.
|
||||
However, the meaning of clock-output-names is domain
|
||||
specific to the clock provider, and is only provided to
|
||||
encourage using the same meaning for the majority of clock
|
||||
providers. This format may not work for clock providers
|
||||
using a complex clock specifier format. In those cases it
|
||||
is recommended to omit this property and create a binding
|
||||
specific names property.
|
||||
|
||||
Clock consumer nodes must never directly reference
|
||||
the provider's clock-output-names property.
|
||||
|
||||
For example:
|
||||
|
||||
oscillator {
|
||||
#clock-cells = <1>;
|
||||
clock-output-names = "ckil", "ckih";
|
||||
};
|
||||
|
||||
- this node defines a device with two clock outputs, the first named
|
||||
"ckil" and the second named "ckih". Consumer nodes always reference
|
||||
clocks by index. The names should reflect the clock output signal
|
||||
names for the device.
|
||||
|
||||
clock-indices: If the identifying number for the clocks in the node
|
||||
is not linear from zero, then this allows the mapping of
|
||||
identifiers into the clock-output-names array.
|
||||
|
||||
For example, if we have two clocks <&oscillator 1> and <&oscillator 3>:
|
||||
|
||||
oscillator {
|
||||
compatible = "myclocktype";
|
||||
#clock-cells = <1>;
|
||||
clock-indices = <1>, <3>;
|
||||
clock-output-names = "clka", "clkb";
|
||||
}
|
||||
|
||||
This ensures we do not have any empty strings in clock-output-names
|
||||
|
||||
|
||||
==Clock consumers==
|
||||
|
||||
Required properties:
|
||||
clocks: List of phandle and clock specifier pairs, one pair
|
||||
for each clock input to the device. Note: if the
|
||||
clock provider specifies '0' for #clock-cells, then
|
||||
only the phandle portion of the pair will appear.
|
||||
|
||||
Optional properties:
|
||||
clock-names: List of clock input name strings sorted in the same
|
||||
order as the clocks property. Consumers drivers
|
||||
will use clock-names to match clock input names
|
||||
with clocks specifiers.
|
||||
clock-ranges: Empty property indicating that child nodes can inherit named
|
||||
clocks from this node. Useful for bus nodes to provide a
|
||||
clock to their children.
|
||||
|
||||
For example:
|
||||
|
||||
device {
|
||||
clocks = <&osc 1>, <&ref 0>;
|
||||
clock-names = "baud", "register";
|
||||
};
|
||||
|
||||
|
||||
This represents a device with two clock inputs, named "baud" and "register".
|
||||
The baud clock is connected to output 1 of the &osc device, and the register
|
||||
clock is connected to output 0 of the &ref.
|
||||
|
||||
==Example==
|
||||
|
||||
/* external oscillator */
|
||||
osc: oscillator {
|
||||
compatible = "fixed-clock";
|
||||
#clock-cells = <0>;
|
||||
clock-frequency = <32678>;
|
||||
clock-output-names = "osc";
|
||||
};
|
||||
|
||||
/* phase-locked-loop device, generates a higher frequency clock
|
||||
* from the external oscillator reference */
|
||||
pll: pll@4c000 {
|
||||
compatible = "vendor,some-pll-interface"
|
||||
#clock-cells = <1>;
|
||||
clocks = <&osc 0>;
|
||||
clock-names = "ref";
|
||||
reg = <0x4c000 0x1000>;
|
||||
clock-output-names = "pll", "pll-switched";
|
||||
};
|
||||
|
||||
/* UART, using the low frequency oscillator for the baud clock,
|
||||
* and the high frequency switched PLL output for register
|
||||
* clocking */
|
||||
uart@a000 {
|
||||
compatible = "fsl,imx-uart";
|
||||
reg = <0xa000 0x1000>;
|
||||
interrupts = <33>;
|
||||
clocks = <&osc 0>, <&pll 1>;
|
||||
clock-names = "baud", "register";
|
||||
};
|
||||
|
||||
This DT fragment defines three devices: an external oscillator to provide a
|
||||
low-frequency reference clock, a PLL device to generate a higher frequency
|
||||
clock signal, and a UART.
|
||||
|
||||
* The oscillator is fixed-frequency, and provides one clock output, named "osc".
|
||||
* The PLL is both a clock provider and a clock consumer. It uses the clock
|
||||
signal generated by the external oscillator, and provides two output signals
|
||||
("pll" and "pll-switched").
|
||||
* The UART has its baud clock connected the external oscillator and its
|
||||
register clock connected to the PLL clock (the "pll-switched" signal)
|
||||
|
||||
==Assigned clock parents and rates==
|
||||
|
||||
Some platforms may require initial configuration of default parent clocks
|
||||
and clock frequencies. Such a configuration can be specified in a device tree
|
||||
node through assigned-clocks, assigned-clock-parents and assigned-clock-rates
|
||||
properties. The assigned-clock-parents property should contain a list of parent
|
||||
clocks in the form of a phandle and clock specifier pair and the
|
||||
assigned-clock-rates property should contain a list of frequencies in Hz. Both
|
||||
these properties should correspond to the clocks listed in the assigned-clocks
|
||||
property.
|
||||
|
||||
To skip setting parent or rate of a clock its corresponding entry should be
|
||||
set to 0, or can be omitted if it is not followed by any non-zero entry.
|
||||
|
||||
uart@a000 {
|
||||
compatible = "fsl,imx-uart";
|
||||
reg = <0xa000 0x1000>;
|
||||
...
|
||||
clocks = <&osc 0>, <&pll 1>;
|
||||
clock-names = "baud", "register";
|
||||
|
||||
assigned-clocks = <&clkcon 0>, <&pll 2>;
|
||||
assigned-clock-parents = <&pll 2>;
|
||||
assigned-clock-rates = <0>, <460800>;
|
||||
};
|
||||
|
||||
In this example the <&pll 2> clock is set as parent of clock <&clkcon 0> and
|
||||
the <&pll 2> clock is assigned a frequency value of 460800 Hz.
|
||||
|
||||
Configuring a clock's parent and rate through the device node that consumes
|
||||
the clock can be done only for clocks that have a single user. Specifying
|
||||
conflicting parent or rate configuration in multiple consumer nodes for
|
||||
a shared clock is forbidden.
|
||||
|
||||
Configuration of common clocks, which affect multiple consumer devices can
|
||||
be similarly specified in the clock provider node.
|
||||
|
||||
==Protected clocks==
|
||||
|
||||
Some platforms or firmwares may not fully expose all the clocks to the OS, such
|
||||
as in situations where those clks are used by drivers running in ARM secure
|
||||
execution levels. Such a configuration can be specified in device tree with the
|
||||
protected-clocks property in the form of a clock specifier list. This property should
|
||||
only be specified in the node that is providing the clocks being protected:
|
||||
|
||||
clock-controller@a000f000 {
|
||||
compatible = "vendor,clk95;
|
||||
reg = <0xa000f000 0x1000>
|
||||
#clocks-cells = <1>;
|
||||
...
|
||||
protected-clocks = <UART3_CLK>, <SPI5_CLK>;
|
||||
};

||||

* 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.
|
||||
- clocks: A list of phandle + clock-specifier pairs for the clocks listed
|
||||
in clock-names
|
||||
- clock-names: Should contain the following:
|
||||
- "xin24m" for both PMUCRU and CRU
|
||||
- "gpll" for CRU (sourced from PMUCRU)
|
||||
- #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,
|
||||

rockchip,grf = <&grf>;
|
||||
#clock-cells = <1>;
|
||||
#reset-cells = <1>;
|

* Rockchip RK3308 Clock and Reset Unit
|
||||
|
||||
The RK3308 clock controller generates and supplies clock to various
|
||||
controllers within the SoC and also implements a reset controller for SoC
|
||||
peripherals.
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible: CRU should be "rockchip,rk3308-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/rk3308-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,
|
||||
- "mclk_i2s0_8ch_in", "mclk_i2s1_8ch_in", "mclk_i2s2_8ch_in",
|
||||
"mclk_i2s3_8ch_in", "mclk_i2s0_2ch_in",
|
||||
"mclk_i2s1_2ch_in" - external I2S or SPDIF clock - optional,
|
||||
- "mac_clkin" - external MAC clock - optional
|
||||
|
||||
Example: Clock controller node:
|
||||
|
||||
cru: clock-controller@ff500000 {
|
||||
compatible = "rockchip,rk3308-cru";
|
||||
reg = <0x0 0xff500000 0x0 0x1000>;
|

rockchip,grf = <&grf>;
|
||||
#clock-cells = <1>;
|
||||
#reset-cells = <1>;
|
||||
};
|
||||
|

description: |
|
||||
Exynos Auto v9 clock controller is comprised of several CMU units, generating
|
||||
clocks for different domains. Those CMU units are modeled as separate device
|
||||
tree nodes, and might depend on each other. Root clocks in that clock tree are
|
||||
two external clocks:: OSCCLK/XTCXO (26 MHz) and RTCCLK/XrtcXTI (32768 Hz).
|
||||
The external OSCCLK must be defined as fixed-rate clock in dts.
|
||||
|
||||
CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
|
||||
dividers; all other clocks of function blocks (other CMUs) are usually
|
||||
derived from CMU_TOP.
|
||||
|
||||
Each clock is assigned an identifier and client nodes can use this identifier
|
||||
to specify the clock which they consume. All clocks available for usage
|
||||
in clock consumer nodes are defined as preprocessor macros in
|
||||
'include/dt-bindings/clock/samsung,exynosautov9.h' header.
