From ecbb1b8d97a78a72003fcb19292da502d393bf80 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Thu, 6 Jul 2017 00:39:29 +0000 Subject: ASoC: hdmi-codec: ELD control corresponds to the PCM stream Current hdmi-codec driver is using hdmi_controls for "ELD" control. But, hdmi-codec driver might be used from many HDMIs. Thus, we need to correspond device number, otherwise we will receive below error. xxx: control x:x:x:ELD:x is already present This patch registers ELD control in .pcm_new by using .device = rtd->pcm->device to corresponding to PCM stream.

Without this patch the codec block will be in reset as long as its not actively used, which means headset events will not be functional if the codec dai is not actively used. Point to note is that the headset detection blocks will work in low power when there is no active audio usecase and switch to micbias source when audio usecase is active. Existing dapms should put the codec in low power state anyway when there is no audio usecase.
