Is it possible to have a binary blob custom control?

[Patrick Doyle <wpdster@xxxxxxxxx>]

I would like to transfer a binary blob of data to my V4L2 device
driver.  Is there a way I can do this through the V4L2 "control"
framework?  Or should I implement a custom ioctl to do that?

Any recommendations or examples?

Thank you.
