Hi guys,
In the context of supporting the control of our HDMI-TX via V4L2 in our
SetTopBox, we are facing interface issue with V4L2 when trying to set some
information from the application into the H/W.
As an example, in the HDCP context, an application controlling the HDMI-TX have

Hello!
I'm trying to implement camera support for my i.MX6 board and cannot

My camera is mt9m001 and i can perfectly find and use it's camera
