NXP NFC Linux Kernel Driver (PN54x / PN55x)

Out-of-tree NXP NFC I²C kernel driver adapted for modern Linux kernels and Android GKI.

This repository is based on the legacy NXP PN54x/PN55x driver and has been updated to build and run on modern Linux kernels (5.10+), including Android GKI.

This project is based on the official NXP PN54x/PN55x I²C driver from the NXPNFCProject.

Original repository: NXPNFC_I2CDriver/tree/br_ar_p_sn1xx

Compared to the original implementation, this repository includes:

• Ported to modern Linux kernels (5.10+)
• Android GKI compatibility fixes
• Updated deprecated kernel APIs
• Build fixes for modern toolchains
• PN557 compatibility improvements
• Stability improvements and bug fixes
• Tested on Linux 5.10.260 GKİ Kernel

The original driver and copyright remain the property of NXP Semiconductors and their respective contributors. This repository distributes a modified version under the terms of the original GPL-2.0 license.

• Linux 5.10+ GKI compatible
• Android 13 / 14 / 15 / 16 compatible
• eSE (Embedded Secure Element) support
• Secure timer support

These chips belong to the same NXP PN54x/PN55x driver family or share a similar software architecture, but have not been physically tested.

SN100, SN110 and SN220 are not claimed as supported, as they have not been verified with this driver.

• Linux 5.10.x (Android GKI)
• Linux 5.15.x
• Linux 6.1.x

Legacy kernels may also work with minimal changes.

Example compatible:

compatible = "nxp,pn544";

or

compatible = "nxp,pn548";

Depending on your board configuration.

This repository only contains the Linux kernel driver.

Android userspace components such as:

• NFC HAL
• libnfc-nci
• Firmware blobs

must be supplied separately by your device vendor or ROM.
