The prior location was somewhat based on the Linux driver location, but bindings should be independent of that.

drm/tilcdc: Add support for external tda998x encoder 2015-05-27T10:13:32+00:00 Jyri Sarha jsarha@ti.com 2015-02-10T12:13:23+00:00 103cd8bc1c80ec0a12ef438c4493f7c26edc71bd Add support for an external compontised DRM encoder. The external encoder can be connected to tilcdc trough device tree graph binding. The binding document for tilcdc has been updated. The current implementation supports only tda998x encoder. To be able to filter out the unsupported video modes the tilcdc driver needs to hijack the external connectors helper functions. The tilcdc installes new helper functions that are otherwise identical to orignals, but the mode_valid() call-back check the mode first localy, before calling the original call-back. The tilcdc dirver restores the original helper functions before it is unbound from the external device. I got the idea and some lines of code from Jean-Francois Moine's "drm/tilcdc: Change the interface with the tda998x driver"-patch.
