Hi all,
I have a question about incorporating existing I2C support in kernel.
1) In order to have working peripherel on I2C bus I have to insmod:
a) i2c-core.o
b) i2c-dev.o
c) i2c-proc.o
d) i2c-<my_board>.o
e) i2c-<my_device>.o
Am I right? Did I miss something?
2)
More important question: I enabled I2C support in make menuconfig, for
I2C code to be built in a kernel, not as a modules. I check <*>
for "I2C device interface", but left unchecked for "I2C Algorithms" and
"I2C Hardware Bus support" since I do not have yet implemented support
for my board (for AMBA bus). Now I can see i2c directory under /sys/bus
(under /dev I can not see anything with i2c name). I'd like to know
which one of these '.o' files got build in a kernel. I suppose
i2c-core.o, i2c-dev.o and i2c-proc.o, and I have to insert then
i2c-<my_board>.o (which I did not checked in menuconfig) and
i2c-<my_device>.o (similar). Am I right?
Also - where can I check for the list of these kenel built-in modules? In /lib/modules I can see only these:
$ pwd
/lib/modules
$ ls
rtai_up.ko rtai_timer_start.ko rtai_hal.ko
$
Where these i2c-*.o files should be kept, after inserted with insmod (or comiled staticaly into a kernel, as in my case).
Cheers,
