[PATCH] drm/i915: move infoframe setting to after pll enable v2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Needs to happen after clock is running or it doesn't behave correctly.

v2: fix subject (Ville)
    make it clearer that this occurs in pre_enable (Paulo)
