Nordic I2S (Inter-IC sound interface)

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`clock-source`	`string`	Clock source to be used by the I2S peripheral for the master clock (MCK) generator. The generator is only needed when the I2S peripheral is operating in Master mode. The following options are available: - "PCLK32M": 32 MHz peripheral clock, synchronous to HFCLK - "PCLK32M_HFXO": PCLK32M running off the 32 MHz crystal oscillator (HFXO) for better clock accuracy and jitter performance - "ACLK": Audio PLL clock with configurable frequency (frequency for this clock must be set via the "hfclkaudio-frequency" property in the "nordic,nrf-clock" node); this clock source is only available in the nRF53 Series SoCs and it requires the use of HFXO Default value: `PCLK32M_HFXO` Legal values: `'PCLK32M'`, `'PCLK32M_HFXO'`, `'ACLK'`
`pinctrl-0`	`phandles`	Pin configuration/s for the first state. Content is specific to the selected pin controller driver implementation.
`pinctrl-1`	`phandles`	Pin configuration/s for the second state. See pinctrl-0.
`pinctrl-2`	`phandles`	Pin configuration/s for the third state. See pinctrl-0.
`pinctrl-3`	`phandles`	Pin configuration/s for the fourth state. See pinctrl-0.
`pinctrl-4`	`phandles`	Pin configuration/s for the fifth state. See pinctrl-0.
`pinctrl-names`	`string-array`	Names for the provided states. The number of names needs to match the number of states.

Deprecated properties not inherited from the base binding file.

Name	Type	Details
`sck-pin`	`int`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. The SCK pin to use. For pins P0.0 through P0.31, use the pin number. For example, to use P0.16 for SCK, set: sck-pin = <16>; For pins P1.0 through P1.31, add 32 to the pin number. For example, to use P1.2 for SCK, set: sck-pin = <34>; /* 32 + 2 */
`lrck-pin`	`int`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. The LRCK pin to use. The pin numbering scheme is the same as the sck-pin property's.
`sdout-pin`	`int`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. The SDOUT pin to use. The pin numbering scheme is the same as the sck-pin property's.
`sdin-pin`	`int`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. The SDIN pin to use. The pin numbering scheme is the same as the sck-pin property's.
`mck-pin`	`int`	IMPORTANT: This option will only be used if the new pin control driver is not enabled. The MCK pin to use. The pin numbering scheme is the same as the sck-pin property's.

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 “nordic,nrf-i2s” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`interrupts`	`array`	interrupts for device This property is required. See Important properties for more information.
`#address-cells`	`int`	number of address cells in reg property This property is required. Constant value: `1`
`#size-cells`	`int`	number of size cells in reg property This property is required.
`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-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
`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.
