I'd like to add a "Common device tree bindings for media devices" topic to the agenda for consideration. There were some activities on creating device tree bindings for Samsung and SH Mobile SoCs but this didn't really kick off yet and a face to face discussions could help to bring device tree support in media subsystem to the level many other subsystems already have. -- Thanks, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
