In these case when module has to bind, then the virtual DSP modules needs to skipped till a actual DSP module is found which connects the pipelines. So we need to walk the graph and find a widget which is real in nature. This patch adds that support and splits skl_tplg_pga_dapm_pre_pmu_event() fn with parsing code to skl_tplg_bind_sinks() fn and call that recursively as well as while parsing The patch moves code a bit while splitting so diffstat doesn't tell real picture Signed-off-by: Jeeja KP Signed-off-by: Vinod Koul --- sound/soc/intel/skylake/skl-topology.c | 133 ++++++++++++++++++++------------- 1 file changed, 83 insertions(+), 50 deletions(-) diff --git a/sound/soc/intel/skylake/skl-topology.c b/sound/soc/intel/skylake/skl-topology.c index abbf8e7eb3e7..0c6e7833e652 100644 --- a/sound/soc/intel/skylake/skl-topology.c +++ b/sound/soc/intel/skylake/skl-topology.c @@ -397,40 +397,24 @@ static int skl_tplg_mixer_dapm_pre_pmu_event(struct snd_soc_dapm_widget *w, return 0; } -/* - * A PGA represents a module in a pipeline.
