We want to implement few custom spi client drivers & corresponding applications.
We would be targeting ADC family in general .
Currently i am going through the standard Linux documentation/spi to get an idea as to how this can be done.
Would request to please let me know if any standard spi client ( protocol) driver is available which i could use as an initial template / reference ?
Idea is to understand the linux kernel standard template to do this task.
SPIDEV is avoided here as we might have to add DMA and few custom data logic.
Hence i am planning to go ahead with SPI slave ( protocol) driver way.
