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.
Why is it too late? -EPROBE_DEFER from this point will cause the driver initialisation to correctly unwind and return -EPROBE_DEFER to the last-to-be-added component.
This fixes probe failure when using the LDB on i.MX6.
More details please.
