st,stm32wb0-rcc
Vendor: STMicroelectronics
Description
STM32WB0 Reset and Clock controller node for STM32WB0 devices
This node is in charge of the system clock ('SYSCLK') source
selection and generation.
Properties
Properties not inherited from the base binding file.

|
Number of items to expect in a Clock specifier
This property is required. Constant value: |
|
|
default frequency in Hz for clock output
This property is required. |
|
|
Slow clock source selection.
On STM32WB0, all slow clock devices are clocked from the same
slow clock source, which is selected by this property.
The slow clock can be either clk_lsi, clk_lse, or clk_16mhz_div512.
|
|
|
CLK_SYS prescaler. Defines actual core clock frequency (CLK_SYS) based
on system frequency input (SYSCLK).
The CLK_SYS is used to clock the CPU, AHB, APB, memories and PKA.
NOTE: if the 32MHz HSE is used as SYSCLK source, the prescaler cannot
be set to 64.
This property is required. Legal values: |
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “st,stm32wb0-rcc” compatible.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
|
List of power states that will disable this device power.
