From: Lucas Stach <l.stach@xxxxxxxxxxxxxx> Since imx_drm_encoder_parse_of is called from the encoder bind callbacks, it is too late to request probe deferral. Rather the core should make sure that the crtcs are bound before the encoders, after all needed components are probed. This fixes probe failure when using the LDB on i.MX6.
