I recently made a set of changes that replaced KEY_MEDIA usage for BTN_0 with KEY_PLAYPAUSE. See https://lkml.org/lkml/2017/11/22/586
Since this patch may be destined for Chrome OS, you should definitely use KEY_PLAYPAUSE, as the Chrome OS user space doesn't respond to KEY_MEDIA but does respond to KEY_PLAYPAUSE.
Thanks, Benson
