The connection as follows: ==> hdmi-codec ==> it6505(HDMI output) DL1(FE) ==> I2S3(BE) ==> rt1015p(SPEAKER output) So in order to separately control their power on/off, we have added a dapm widget to notify each output. Also the machine driver need add a _PIN_SWITCH() on the output of the device that will cause DAPM to keep the device powered down when not in use. The purpose of adding .trigger callback here is to enable hdmi-codec to notify the dp output driver to power on or off device.
