Are we talking > about migrating each soc-camera sensor separately, soc-camera > framework changes, both of them? Both actually. The soc-camera core and soc-camera hosts first need to be extended to support both pad-aware and non pad-aware subdevs. Guennadi gave that a thought some time ago, I'm not sure what the status is. Then the soc-camera platform data need to be split in a sensor part and a host part. This is required for DT support as well, so work is ongoing there. Finally your sensor driver will need to implement pad operations. -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
