Description

These nodes are “i2s” bus nodes.

Nordic TDM (Time division multiplexed audio interface)

Properties

Properties not inherited from the base binding file.

Name

Type

Details

mck-frequency

int

Frequency of the MCK clock. Configured independently of SCK.

pinctrl-0

phandles

Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.

This property is required.

pinctrl-names

string-array

Names for the provided states. The number of names needs to match the
number of states.

This property is required.

easydma-maxcnt-bits

int

Maximum number of bits available in the EasyDMA MAXCNT register. This
property must be set at SoC level DTS files.

This property is required.

mck-clock-source

string

Clock source to be used by the MCK signal. The following options
are available:
- "PCLK": Peripheral clock
- "ACLK": Audio PLL clock with configurable frequency (frequency for
  this clock must be set via the "frequency" property
  in the "nordic,nrfs-audiopll" node).

Default value: PCLK

Legal values: 'PCLK', 'ACLK'

sck-clock-source

string

Clock source to be used by the SCK signal. The following options
are available:
- "PCLK": Peripheral clock
- "ACLK": Audio PLL clock with configurable frequency (frequency for
  this clock must be set via the "frequency" property
  in the "nordic,nrfs-audiopll" node).

Default value: PCLK

Legal values: 'PCLK', 'ACLK'

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.

nordic,clockpin-enable

array

List of signals that require CLOCKPIN setting enablement.

memory-regions

phandle-array
