NXP NFC version and ACPI

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

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
