Need to know code flow spi driver

Started by Ravi Gupta November 20, 2012









Hi all,

I am trying to see how a spi driver is registered as character device. In linux kernel 2.6.25, in drivers\spi\atmel_spi.c, in the probe function I could not find spi_register_driver(). I would also like to know the code flow for how spi driver registers itself as character device.

 

Thanks & Regards,

Ravi Gupta

Hi Ravi,
See the file drivers/spi/spidev.c
Atmel_spi.c is a platform driver and not a spi client driver.
