I would like to use this letter to explain what this patche does. (Note its tested on Carrizo & Stoney) * Firstly it decouples the per-plane per-crtc design, as a result, now with the unit test called as 'modetest' we can see 3 planes and 2 crtc's compared to what it was 2 planes for 2 crtc's w/o this patch. * I have introduced new variable of max_surfaces to the public caps structure that can be used for all asic's in future as well. Basic understanding being: max_streams == crtc link_count == connector max_surfaces == plane * The drm device initialization loops now for number of surfaces instead of stream. * Have taken care that it won't break other asic's * Am able to reach __setplane_internal() in drm_plane.c which does the final update to plane, had to put a sanity patch there as we do not have update_plane() and disable_plane() implemented --> also testifies, that now we are able to handle planes with this patch. * The YUV formats supported right now are default, will refine it going further.
