主题： how can i use spi in dm355?
dear all:
I am using mv_pro_4.0.1 in dm355 platform,now i want to use spi0 and
spi1 to communication with other devices which is like using i2c open() ,
read() ,and write() to various device by sub address in userspace. My linux
kernel is 2.6.10,I have find the spidev.c and spidev_test.c in linux2.6.30,So i
have transplanted the spidev.c as a module in linux kernel 2.6.10,but when i
insmod the module,i cann't find the needful device in /dev/ path,so i cann't
run spidev_test.c to test spi,I think there may be some errors in dm355 device
driver,but i don't know how to modify it? Any help will be appreciated!
