The simple-kms helper provides a reset_plane hook to let drivers override the default plane reset. However, the reset hook is overloaded: it is used to create the initial software state at probe time, but also to reset both the hardware and software state during suspend/resume. These two roles have different expectations, and reset is not fallible which makes error handling difficult. The atomic_create_state pattern was introduced to untangle this by providing a hook that only allocates and initializes a pristine state without any side effect. Add a create_plane_state hook to struct drm_simple_display_pipe_funcs. When provided, drm_simple_kms_plane_reset() will use it to allocate a fresh state, falling back to reset_plane and then to the default drm_atomic_helper_plane_reset(). This will allow simple-kms drivers to be converted to the atomic_create_state pattern.
