Yes, gpio 0-4 are connected to NFC eSE and gpio 30-34 are for
fingerprint scanner. Here is the list of reserved gpio and their
functions according to the device's schematic.
0 - ESE_SPI_MISO
1 - ESE_SPI_MOSI
2 - ESE_SPI_SCLK
3 - ESE_SPI_CS_N
30 - FP_SPI_MISO
31 - FP_SPI_MOSI
32 - FP_SPI_SCLK
33 - FP_SPI_CS_N
Though Redmi Note 8 does not have NFC, kernel crashes if 0-4 gpios
are not reserved.
