[PATCH v3 09/18] drm/i915: move and group power related members under display.power

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

 



Move display power related members under drm_i915_private display
sub-struct.

Arguably chv_phy_control and chv_phy_assert could be placed in a phy
substruct, but they are only used in the power code.
