[PATCH v3 02/22] drm/i915: get rid of intel_crtc_disable and related code, v2

Maarten Lankhorst
2015-05-20T13:38:37Z

Now that the dpll updates are (mostly) atomic, the .off() code is a noop,
and intel_crtc_disable does mostly the same as intel_modeset_update_state.

Move all logic for connectors_active and setting dpms to that function.

Changes since v1:
- Move drm_atomic_helper_swap_state up.
Changes since v2:
- Split out intel_put_shared_dpll removal.
