[PATCH 5/5] ASoC: qcom: apq8016-sbc: Map BTN_0 to KEY_PLAYPAUSE

From: Benson Leung
Date: Wed Nov 22 2017 - 15:57:05 EST


The Android 3.5mm Headset jack specification mentions that BTN_0 should
be mapped to KEY_MEDIA, but this is less logical than KEY_PLAYPAUSE,
which has much broader userspace support.

For example, the Chrome OS userspace now supports KEY_PLAYPAUSE to toggle
play/pause of videos and audio, but does not handle KEY_MEDIA.

Furthermore, Android itself now supports KEY_PLAYPAUSE equivalently, as the
new USB headset spec requires KEY_PLAYPAUSE for BTN_0.
