st,stm32-clock-mux
Vendor: STMicroelectronics N.V.
Note
An implementation of a driver matching this compatible is available in drivers/clock_control/clock_stm32_mux.c.
Description
STM32 Clock multiplexer
Describes a clock multiplexer, such as per_ck on STM32H7 or
CLK48 on STM32L5.
The only property of this node is to select a clock input.
For instance:
&perck {
clocks = <&rcc STM32_SRC_HSI_KER CKPER_SEL(0)>;
status = "okay";
};

Indicates the operational status of the hardware or other
resource that the node represents. In particular:
- "okay" means the resource is operational and, for example,
can be used by device drivers
- "disabled" means the resource is not operational and the system
should treat it as if it is not present
For details, see "2.3.4 status" in Devicetree Specification v0.4.

This property is a list of strings that essentially define what
type of hardware or other resource this devicetree node
represents. Each device driver checks for specific compatible
property values to find the devicetree nodes that represent
resources that the driver should manage.
The recommended format is "vendor,device", The "vendor" part is
an abbreviated name of the vendor. The "device" is usually from
the datasheet.
The compatible property can have multiple values, ordered from
most- to least-specific. Having additional values is useful when the
device is a specific instance of a more general family, to allow the
system to match the most specific driver available.
For details, see "2.3.1 compatible" in Devicetree Specification v0.4.
This property is required. See Important properties for more information. |
