44 * DOC: atomic state reset and initialization
47 * and correct atomic software state for all connectors, CRTCs and planes
49 * suspend. One way to solve this is to have a hardware state read-out
50 * infrastructure which reconstructs the full software state (e.g. the i915
53 * The simpler solution is to just reset the software state to everything off,
57 * On the upside the precise state tracking of atomic simplifies system suspend
65 * __drm_atomic_helper_crtc_state_reset - reset the CRTC state
66 * @crtc_state: atomic CRTC state, must not be NULL
70 * values. This is useful for drivers that subclass the CRTC state.
