With commit "drm: atmel-hlcdc: enable clock before configuring timing engine" there is no need for this patch. Code is also simpler. Cc: Sandeep Sheriker Mallikarjun Signed-off-by: Claudiu Beznea --- Hi Sam, I still kept this as a patch as I didn't got any answer from you at my last email up to this moment. If you think it is better to squash this one with patch 2/6 in this seris let me know.
