Hi,I want to creat a device node in my /dev so that I can open it from userspace or do something,I also config the kernel like this:
Device Drivers --->
[*] SPI support --->
<*> SPI controller driver for ADI Blackfin5xx /* choose this for bf5xx soc */
<*> User mode SPI device driver support /* user space spi driver
and modfiy the ezbrd.c like this:
.modalias = "spidev",
.max_speed_hz = 3125000, /* max spi clock (SCK) speed in HZ */
.bus_num = 1,
.chip_select = 1,
.controller_data = &spidev_chip_info,
but I can't fide any devcive about the spi in /dev dir.
I find in the driver code can call the device_create to creat the device,but when and where to call the spidev_probe fun?
