The Cirrus Logic Madera codecs are a family of related codecs with extensive digital and analogue I/O, digital mixing and routing, signal processing and programmable DSPs. This patch adds common support code shared by all Madera codecs. This patch also adds the pdata to the parent mfd pdata struct. Since there is a circular build dependency it's convenient to patch them both atomically.

|
|
* @max_channels_clocked: Maximum number of channels that I2S clocks will be
|
|
* generated for. Useful when clock master for systems
|
|
* where the I2S bus has multiple data lines.
|
|
* @dmic_ref: Indicates how the MICBIAS pins have been externally
|
|
* connected to DMICs on each input. A value of 0
|
|
* indicates MICVDD and is the default. Other values are:
|
|
* For CS47L35 one of the CS47L35_DMIC_REF_xxx values
|
|
* For all other codecs one of the MADERA_DMIC_REF_xxx
|
|
* Also see the datasheet for a description of the
|
|
* INn_DMIC_SUP field.
|
|
* @inmode: Mode for the ADC inputs. One of the MADERA_INMODE_xxx
|
|
* values. Two-dimensional array
|
|
* [input_number][channel number], with four slots per
|
|
* input in the order
|
|
* [n][0]=INnAL [n][1]=INnAR [n][2]=INnBL [n][3]=INnBR
|
|
* @out_mono: For each output set the value to TRUE to indicate that
|
|
* the output is mono. [0]=OUT1, [1]=OUT2, ...
|
|
* @pdm_fmt: PDM speaker data format. See the PDM_SPKn_FMT field in
|
|
* the datasheet for a description of this value.
|
|
* @pdm_mute: PDM mute format. See the PDM_SPKn_CTRL_1 register
|
|
* in the datasheet for a description of this value.
