Hey, there is a nice official nxp driver at https://github.com/NXPNFCLinux/nxp-pn5xx compared to misc device driver from an lg kernel, should be much better.
Crap, it is basically the same driver as used in LG kernel. Good news is that pn544 and pn547 might be compatible
Some info on linux nfc stack https://elinux.org/images/d/d1/Near_Field_Communication_with_Linux.pdf
