Hello,
Private controls must not be used. LED control should be generic (I
have many requests for that).
In March 2009, I proposed to add a V4L2_CID_LEDS control ("[PATCH] LED
control"), but someone told me to use the sysfs led interface instead.
After looking at this interface, I thought it was too complex for our
purpose and no easy for the users.
Maybe it is time to argue again...
Cheers.
