Hi Guys,
I have a pretty general question about the spi framework.
I hope this is not off topic for this list.
So it is about uclinux kernel 2.6.28 for blackfin cpu.
1. I undestand how to define my spi data in the board file.
2. I have kernel device driver for my spi chip.
3. I have read about linux/spi/spi.h and the spi protocol driver API which
is exported.
spi_read(struct spi_device *spi, u8 *buf, size_t len)
spi_write(struct spi_device *spi, const u8 *buf, size_t len)
etc ...
I would like to use this API from another kernel module (so kernel space)
For me it is unclear however how to get pointer to spi_device from my kernel
module. In general is there somewhere an example for using of the spi framework
from the kernel space.
I don't want to write spi device drivers. It is already written in the linux
tree. I would like to use it from the kernel space.
Thank you for all pointers you provide!
Dimitar
