That works, and this works:

ver working with variable sensors

About v4l2_dv_timings, do I need to set a default timing similar to
pick PAL as default standard?
Thanks,

Sounds reasonable.

The problem is you can't get version before power up device but you
should apply patch
erate other i2c maps. Is it acceptable or any
other suggestion?
By the way, HDMI support seems under discussion, is there any
framework or guide now?
Thanks,

Hi Hans and Guennadi,
Our bridge driver needs to know line clock count including active
lines and blanking area.
I can compute active clock count according to pixel format, but how
can I get this in blanking area in current framework?
Thanks,

list_is_singular accepts a list head to test whether a list has just one entry.
fh->list is the entry, fh->vdev->fh_list is the list head.

Hi Sakari,
Hans recommends me using v4l2_fh_is_singular in first open, but I
found it used list_is_singular(&fh->list).
Should it use &fh->vdev->fh_list or I missed something?

Scott
