You used clk_prepare and clk_unprepare instead of clk_prepare_enable and clk_disable_unprepare. I didn't check the dss driver yet, but my hunch is that the clocks are normally not enabled/disabled from atomic context. What does the prepare/unprepare actually do? Is there any benefit in delaying preparing, i.e. is there a difference between prepare right after clk_get, or prepare right before clk_enable? (And similarly for unprepare) Tomi
