Series omapdrm: Rework the timing-related operations | expand

Commit Message

Laurent Pinchart Aug. 6, 2018, 8:36 p.m. UTC 
The drm_connector implementation requires access to the omap_dss_device
corresponding to the display, which is passed to its initialization
function and stored internally. Refactoring of the timings operations
will require access to the output omap_dss_device. To prepare for that,
pass it to the connector initialization function and store it internally
as well.
