[PATCH 23/23] drm/omap: Don't call .set_timings() operation recursively
Laurent Pinchart
laurent.pinchart at ideasonboard.com
Fri Jun 8 16:29:26 UTC 2018
Instead of calling the .set_timings() operation recursively from the
display device backwards, iterate over the devices manually in the DRM
encoder code. This moves the complexity to a single central location and
simplifies the logic in omap_dss_device drivers.
