This describes audio configuration bindings for these codecs.

description:

A list of input mode settings for each input. A maximum
|
||
|
|
of 24 cells, with four cells per input in the order INnAL,
|
||
|
|
INnAR INnBL INnBR. For non-muxed inputs the first two cells
|
||
|
|
for that input set the mode for the left and right channel
|
||
|
|
and the second two cells must be 0. For muxed inputs the
|
||
|
|
first two cells for that input set the mode of the left and
|
||
|
|
right A inputs and the second two cells set the mode of the
|
||
|
|
left and right B inputs. Valid mode values are one of the
|
||
|
|
MADERA_INMODE_xxx. If the array is shorter than the number
|
||
|
|
of inputs the unspecified inputs default to MADERA_INMODE_DIFF.

A value of 0 indicates MICVDD and is the default,

other values depend on the codec: For CS47L35 one of the

CS47L35_DMIC_REF_xxx values For all other codecs one of

|
|
the MADERA_DMIC_REF_xxx values Also see the datasheet for a

description of the INn_DMIC_SUP field.
