ts3a227e datasheet says typical key resistance is key1 50 Om
It is a misspelling in the commit message. "Om" should be replaced with "Ohm" here and below.
Mark are you ok to fix it in your repo or do you want me to resend the updated patch?
key2 135 Om key3 240 Om key4 470 Om
The android headset specification expect buttons impedance: A (MEDIA) 0-70 Om D (VOICECOMMAND) 110-180 Om B (VOLUMEUP) 210-290 Om C (VOLUMEDOWN) 360-680 Om
Thus key mapping should be key1 - MEDIA key2 - VOICECOMMAND key3 - VOLUMEUP key3 - VOLUMEDOWN
