Hi,

the discussion reference is on github [1].

I acquired a Lenovo x280 with a NFC chip. It is unclear what chip is it
really, it is called NXP NPC300 which could be a PN7xxx chip range.

A hacked version of an old deprecated out-of-tree module made the PN5xxx
to work with my laptop but I suspect it brought some subtle instability
on my system.

Now it would be nice to have this correctly supported upstream.

Since all other PC vendors have ceased supporting NFC (Intel made it useless), why bother?

I dumped the ACPI DSDT table and got the id NXP1001. This one is not
listed in the match table of the nxp-nci driver.

  - is the driver missing for the so called NXP NPC300 ?
  - should the NXP1001 matching string to be added to nxp-nci?
  - is my firmware sending me garbage ?

Thanks in advance for any input
