Maxime Ripard 7e5d178cbc drm/crtc: Introduce hw_reset helper hook ... The CRTC reset hook conflates initial software state allocation with hardware reset. The atomic_create_state hook addresses the software state side, but drivers may still need to reset hardware to a known good state during drm_mode_config_reset(), for example during suspend/resume. Separating hardware reset from state allocation is also useful for the pending atomic state readout and userspace atomic reset flag series, which need to create pristine software state without affecting the hardware. Introduce a hw_reset hook in struct drm_crtc_helper_funcs that only resets the hardware, without touching the software state at all. Call it from drm_mode_config_crtc_reset_with_create_state() after the state has been successfully created.
