How to add new chip ids to v4l2-chip-ident.h ?
Hi,
I would like to know how to add new chip ids to v4l2-chip-ident.h. Ist there a kind of policy for choosing numbers ?
Which numbers would be approriate for the em25xx/em26xx/em27xx/em28xx chips ?
Unfortunately 2700 is already used by V4L2_IDENT_VP27SMPX...
Regards,
Frank Schäfer

Using numbers that match the chip number is recommended, but if that can't be done due to clashes, then pick some other, related, number (e.g. 12700 instead of 2700) or create a range of number for all possible models of that chip series.

Please note that adding an identifier to v4l2-chip-ident.h is only needed if the VIDIOC_DBG_* ioctls are implemented. If those are not implemented, then there is no need for an ID either.

Ok. And I guess a comment should be added that reserves a certain range of values, if similar chips exist.
