st,stm32wl-rcc¶

Description¶

STM32WL Reset and Clock controller node.
For more description confere st,stm32-rcc.yaml

Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`ahb3-prescaler`	`int`	HCLK3 shared prescaler (AHB3, Flash memory, SRAM1 and SRAM2). (A.K.A SHDHPRE) Legal values: `1`, `2`, `4`, `8`, `16`, `32`, `64`, `128`, `256`, `512`
`cpu1-prescaler`	`int`	CPU1 prescaler. Sets a HCLK1 frequency (feeding Cortex-M Systick) lower than SYSCLK frequency (actual core frequency). Zephyr doesn't make a difference today between these two clocks. Changing this prescaler is not allowed until it is made possible to use them independently in Zephyr clock subsystem. HCLK1 clocks CPU1, AHB1, AHB2, AHB3 and SRAM1. Legal values: `1`
`cpu2-prescaler`	`int`	CPU2 prescaler. Sets HCLK2 frequency which clocks CPU2. (A.K.A C2HPRE) Legal values: `1`, `2`, `4`, `8`, `16`, `32`, `64`, `128`, `256`, `512`
`#clock-cells`	`int`	Number of items to expect in a Clock specifier This property is required. Constant value: `2`
`clock-frequency`	`int`	default frequency in Hz for clock output
`apb1-prescaler`	`int`	Legal values: `1`, `2`, `4`, `8`, `16`
`apb2-prescaler`	`int`	Legal values: `1`, `2`, `4`, `8`, `16`

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,stm32wl-rcc” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
