Hi,
Sort of a basic v4l2/soc-camera question.
First time posting on this mailing list; Let me know if this not the
right forum to post.
I am working on an old platform software based on kernel 3.6;
in my case, I have host driver and an i2c sub device driver (based on 5640)
Both are .ko (loadable kernel modules).
Now, things are working if
I load sub device driver first, and then host driver.
But, if i load host driver first,and then sub device driver, then
things are not fine.
first while insmod-ing host driver itself, probe of host driver is called,
and soc_camera_host_register() is returning fine; internally within
soc_camera.c it would have failed.
Here: @
Soc_camera_probe()
if (icl->board_info) {
ret = soc_camera_init_i2c(icd, icl); // this would
fail as i2c sub device is not added;
if (ret < 0)
{
goto eadddev;
}
Is this expected, ? Or, the probe of host driver itself shoudn't have called?!
Is there any loading order of host/ sub device driver. etc?
Thanks,
Sherin
