Subject: Change MODE, CS, BUS, and SPEED using SPI-DEV driver?
Date: Fri, 01 Oct 2010 13:40:31 -0400 [thread overview]
Message-ID: <20101001175135.147160@gmx.com> (raw)
I have built a linux kernel using only the "S3C6410 High Speed SPI Driver." Debug messages were enabled.
In the ./drivers/spi directory, the following were built: built-in.o hspi-s3c64xx.o spi-dev.o spi.o
When I open the driver from a user space application, the debug statements come from the SPI-DEV driver.
However, I don't see the IOCTL calls in spi-dev.c to change the MODE, CS, BUS, or SPEED. I also need to use two speeds, high and low.
The question I have is how do I modify these settings?
Thanks in advance.
