Instead of adding code to have the slave encoder working, it would be
simpler to change the way tilcdc uses the tda998x.
I already proposed such a patch:

http://lists.freedesktop.org/archives/dri-devel/2014-March/056065.html

and the changes in the tda998x driver have been done by Russell:

commit: a8f4d4d63739e4bca459ff40636f1d9e4b7ef5e6
	drm/i2c: tda998x: allow re-use of tda998x support code
and
commit: c707c3619ca81f499a5ce032021405e989a96ff0
	drm/i2c: tda998x: add component support
