NFC does not work (compared to Nebula Kernel)

NFC does not work. I used your kernel (with KernelSU support), taken from there:
https://4pda.to/forum/index.php?showtopic=1051332&st=3670#entry140513687

Kernel:
5.4.302-Starry私はあなたのものです-gdcf9257df718-dirty
#1 Thu Dec 25 18:54:27 IST 2025

Device: veux, global version (bought in Russia)

OS: LineageOS 23.0 unofficial (Android 16)
taken from there:
https://4pda.to/forum/index.php?showtopic=1051332&st=3690#entry140807380

Issue:
NFC toggle does not turn on in settings. Cards are not readable. NFC does not work in short

BUT, with nebula-r07-veux-20251010-0607 kernel nfc works. The kernel is taken from there:
https://4pda.to/forum/index.php?showtopic=1051332&st=3260#entry136028677

Technical comparison:
I checked /proc/config.gz on both kernels. It seems Starry is missing the specific driver for the NFC chip (PN557) used in the global veux variant.

Starry kernel config:

# CONFIG_NFC is not set
CONFIG_NFC_QTI_I2C=y
# CONFIG_NFC_QTI_I3C_GPIO is not set

Nebula kernel config (Working NFC):

# CONFIG_NFC is not set
CONFIG_NFC_QTI_I2C=y
CONFIG_NFC_PN557=y  <-- this driver is present in Nebula but missing in Starry
# CONFIG_NFC_QTI_I3C_GPIO is not set

ALSO, on Starry, getprop | grep nfc does not show [nfc.initialized]: [true], while it does on Nebula.

please add CONFIG_NFC_PN557=y to the veux defconfig.
