What that reveals is that *no* 32-bit> dts files contain the compatible string, and so I summise that *no*> 32-bit iMX SoC should have this driver enabled. The problem is a bit more generic. I often have to spend lots of time to find out which configs to enable on a specific board, to get certain features (eg. network, sata, display, gpu, ...). Even worse: many options require other stuff enabled before even showing up. And when disabling unneeded stuff, it leaves lots of other things enabled. (we don't have some `apt autoremove` kconfig counterpart :().
I've decided to cope w/ that on a higher level and written a little config generator tool for that - here you can enable high level features (eg. 'network' or 'display', etc) and it will generate the actual .config:

Maybe this actually means "nobody here volounteered to actually maintain these help texts" ?

They'll propably tell you if it's incorrect.
