Look at the patchset "[PATCH v2 00/12] NFC: nxp-nci: clean up and support new ID". I have tested on top of Linux v5.1.1. Here I have set... scripts/config -m NFC_NCI -m NFC_NXP_NCI -m NFC_NXP_NCI_I2C -e PINCTRL_SUNRISEPOINT Please give this a try and report. For details see the below references. Thanks.
