I still have some basic questions:
- What are the typical usages for aux_dev? For CODEC<->CODEC link or external headset detection chip?
Neither, it's for analogue devices.
Got it. Thanks!
- Why we need the rtd array 'rtd_aux' for the aux_devs? If the codec has DAIs and used by a DAI link, the ASoC will create a rtd
for the link.
There are (or were at the time) assumptions in drivers that there will be a rtd there so it was easier to provide a stub.
Can we remove this rtd array if current driver does not need the stub?
For the replacement of aux_dev by aux_component, can we define like below?
struct snd_soc_aux_component { const char *comp_name; ... no longer assume they're only codecs const char *comp_of_node;
/* machine specific init */ int (*init)(struct snd_soc_component *componnent); };
The ASoC can use the comp_name or comp_of_node to find the components and probe them.
Thanks Mengdong
