On systems with 2 TCONs such as the A31, it is possible to demux the output of the TCONs to one encoder. Add support for this for the A31.

Would that make sense to make it a bit more generic, and pass the id to look for as an argument? -- Maxime Ripard, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
