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.
