I have a minix neo a2 remote plugged to a non minix device. I managed to get almost every button working. I took the .kl file from the ROM of a minix device, but still there were a few non working keys. Then I made some manual modifications to the kl file, and now it's all good. I share my version in case it might be useful to anyone.
It must be placed in /system/usr/keylayouts/Vendor_0c40_Product_7a18.kl
The only button with some remaining issues is the power button. It works for power off, but does not work for power on.
Other issue with this remote on non minix device is the USB audio feature. Headphone and mic on remote does not work, but they take priority over the default audio card of the device.. so I got no audio on my TV. To quickly solve this I disabled USB audio output by commenting the relative lines in /etc/audio_policy.conf
