Name

Type

Details

linked-terminal

phandle

 
Input or Output Terminal to which this interface is connected.

This property is required.

active-alternate-setting-control

string

 
Active Alternate Setting Control capabilities

Legal values: 'read-only'

valid-alternate-settings-control

string

 
Valid Alternate Settings Control capabilities

Legal values: 'read-only'

external-interface

boolean

 
Enable if audio stream is not transmitted over USB (Type IV Audio Stream).

implicit-feedback

boolean

 
Enable implicit feedback on asynchronous endpoint. For IN endpoints this
sets endpoint behaviour type to implicit feedback data endpoint. For OUT
endpoints setting this property removes explicit feedback endpoint.

pitch-control

string

 
Pitch Control capabilities

data-underrun-control

string

 
Data Underrun capabilities

Legal values: 'read-only'

lock-delay

int

 
Time it takes this endpoint to reliably lock its internal clock recovery
circuitry. Units depend on the lock-delay-units field. Relevant only if
linked-terminal's clock is sof-synchronized.

lock-delay-units

string

 
Units for lock-delay parameter.

Legal values: 'milliseconds', 'decoded-pcm-samples'

subslot-size

int

 
Number of bytes occupied by one audio subslot. Can be 1, 2, 3 or 4.
