2008-04-17 04:33:37     how to use i2c TWI interface in kernel space

William MARTIN (FRANCE)

Message: 54395    hello,

 

I'm writing a driver for NXP16IS752, it's a dual UART over i2c, compatible with 16550 registers.

The interface with the TTY layer works fine, but i'm searching how to use the i2c bus in the kernel space.

 

This doc describe only how to use i2c in user space

http://docs.blackfin.uclinux.org/doku.php?id=i2c

 

I'm working with the SVN trunck.

 

Thanks,

William

Message: 54433    umm, it's the other way around.  that document describes how to do it in kernel space, not user space.
