What is the difference with kbl_da7219_max98357a? the amps are on the 
same SSP but with a two amps instead of one.

Could this be converged so that we avoid 90+ % copy/paste just to change 
a component?

Wrong location, you need to add this in the KBL parts.

this needs to go, this is the "old-style", SND_SOC_INTEL_SST is already 
selected at a higher level.

usually the last two are before HDMI?

this looks like the "old order", this has changed to

  	snd_jack_set_key(jack->jack, SND_JACK_BTN_0, KEY_PLAYPAUSE);
	snd_jack_set_key(jack->jack, SND_JACK_BTN_1, KEY_VOLUMEUP);
	snd_jack_set_key(jack->jack, SND_JACK_BTN_2, KEY_VOLUMEDOWN);
	snd_jack_set_key(jack->jack, SND_JACK_BTN_3, KEY_VOICECOMMAND);

see e.g ('ASoC: Intel: kbl_da7219_max98927: fix the audio jack button 
remapping')

i remember asking that existing machine drivers be realigned (which 
didn't happen btw), let's make sure new drivers are aligned from Day 1
