Now we can replace Codec to Component. Let's do it. Note: xxx_codec_xxx() -> xxx_component_xxx() .idle_bias_off = 0 -> .idle_bias_on = 1 .ignore_pmdown_time = 0 -> .use_pmdown_time = 1 - -> .endianness = 1 - -> .non_legacy_dai_naming = 1 Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>

|
|
* Notes:
|
|
* The WM8753 is a low power, high quality stereo codec with integrated PCM
|
|
* codec designed for portable digital telephony applications.
|
|
*
|
|
* Dual DAI:-
|
|
*
|
|
* This driver support 2 DAI PCM's. This makes the default PCM available for
|
|
* HiFi audio (e.g. MP3, ogg) playback/capture and the other PCM available for
|
|
* voice.
|
|
*
|
|
* Please note that the voice PCM can be connected directly to a Bluetooth
|
|
* codec or GSM modem and thus cannot be read or written to, although it is
|
|
* available to be configured with snd_hw_params(), etc and kcontrols in the
|
|
* normal alsa manner.
|
|
*
|
|
* Fast DAI switching:-
|
|
*
|
|
* The driver can now fast switch between the DAI configurations via a
|
|
* an alsa kcontrol. This allows the PCM to remain open.
