dpcm_end_walk_at_be() stops the graph walk when first BE is found for
the given FE component. In a component model we may want to connect
multiple DAIs from different components.
android_vh_snd_soc_card_get_comp_chain can be registered here
to allows DAI/component chaining.
Later PCM operations can be called for all these listed components for a
valid DAPM path.
ALSA machine driver can setup component_chaining like below code slice.
static void my_board_component_chaining_hook(void *data, bool *ret)
{
*ret = true;
}
static int my_board_dev_probe(struct platform_device *pdev)
{
register_trace_android_vh_snd_soc_card_get_comp_chain(
my_board_component_chaining_hook, NULL);
return 0;
}
static int my_board_dev_remove(struct platform_device *pdev)
{
unregister_trace_android_vh_snd_soc_card_get_comp_chain(
my_board_component_chaining_hook, NULL);
return 0;
}
static struct platform_driver my_board_driver = {
...
.probe = my_board_dev_probe,
.remove = my_board_dev_remove,
...
};
