[alsa-devel] [PATCH] ASoC: Intel: kbl_da7219_max98357a: Map BTN_0 to KEY_PLAYPAUSE
From: Mac Chiang mac.chiang@intel.com
On kbl_rt5663_max98927, commit 38a5882e4292 ("ASoC: Intel: kbl_rt5663_max98927: Map BTN_0 to KEY_PLAYPAUSE") This key pair mapping to play/pause when playing Youtube
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. https://source.android.com/devices/accessories/headset/usb-headset-spec
The same fix is required on Chrome kbl_da7219_max98357a.

this is aligned with a recent patch for the same headset for an AMD platform. We'd need the same fix for the bxt_da7219 machine driver btw. Naveen, is this something you can look into? Thanks!

Agreed Pierre, earlier I have submitted a patch on this for bxt_da7219 - https://patchwork.kernel.org/patch/10335295/ Also I have updated the same for recently ack'd glk_rt5682_max machine.

Right, but neither of those patches were merged? I may be mistaken but this code wasn't in Mark's tree when I looked yesterday.
