May I ask which driver file to add a new DAPM widget? Is it the bridge ic driver like it6505.c? Or is it linke the "SDB" added in this patch?
I would expect this to follow a similar pattern to everything else with hdmi-codec.c and have the actual ASoC stuff in there with a callback exposed to the rest of the world.
Yes, I should add a new set of events, such as: enum { HDMI_CODEC_TRIGGER_EVENT_STOP, HDMI_CODEC_TRIGGER_EVENT_START, HDMI_CODEC_TRIGGER_EVENT_SUSPEND, HDMI_CODEC_TRIGGER_EVENT_RESUME, } Then provide handles for these events in the it6505 driver. Am I right?
I'd expect more like on/off for a DAPM widget (the DAPM callbacks are pre/post on/off) but yes.
Dear mark, I apologize for the delay in responding to this issue, as we have recently encountered the same problem again. I would like to have your guidance on this issue once more. Let me describe the problem we encountered again.
==> "hdmi-audio-codec"(it6505 plug-in) DL1(FE) ==> I2S1(BE) ==> "rt1019p"(Speaker Codec)
I want to independently control the switches for the speaker and hdmi, and realize that when HDMI is plugged in, I can switch to speaker playback, and I can also switch back to hdmi playback too. Of course, I2S1 is used for playback at this time.
So I want to ask if I can do it by just adding SOC_DAPM_PIN_SWITCH("Speakers") and SOC_DAPM_PIN_SWITCH("HDMI")? Correspondingly, dapm widget and route path need to be added. That is "SND_SOC_DAPM_SPK("Speakers", NULL)/ SND_SOC_DAPM_LINE("HDMI1", NULL)" and "{"Speakers", NULL, "Speaker"}/ {"HDMI1", NULL, "TX"}".
If the above is not enough, what else should I modify? hdmi-codec.c or it6505.c? Looking forward to getting you reply, Thank you.
