Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`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`
`ahb3-prescaler`	`int`	HCLK3 shared prescaler (AHB3, Flash memory, SRAM1 and SRAM2). (A.K.A SHDHPRE) This property is required. 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). The HCLK1 clocks CPU1, AHB1, AHB2, AHB3 and SRAM1. This property is required. Legal values: `1`, `2`, `3`, `4`, `5`, `6`, `8`, `10`, `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 This property is required.
`apb1-prescaler`	`int`	This property is required. Legal values: `1`, `2`, `4`, `8`, `16`
`apb2-prescaler`	`int`	This property is required. 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
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`wakeup-source`	`boolean`	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.
`power-domain`	`phandle`	Power domain the device belongs to. The device will be notified when the power domain it belongs to is either suspended or resumed.
