Hi Jack

spi driver is implemented as spi sub-system in Linux, spi driver layer is located between the
client layer (for example pmic or spi flash). It may not implement device node entry.
As example one can look at Chapter 31 SPI NOR Flash Memory Technology Device (MTD) Driver attached
Linux Manual.

alternatively one can look at using spidev :
