Could you please add that? > > Do you think it is necessary to mention also allowed step for all the > values? That's a good question. They probably are more or less visible in the driver code. I think I'd document them here, but I'm fine with not adding them as well. You probably wouldn't be able to meaningfully use the chip without the datasheet anyway. > >Is the datasheet publicly available btw.? > > I have an access only to the non-public one. I googled a bit, couldn't find anything relevant immediately at least. -- Regards, Sakari Ailus e-mail: sakari.ai...@iki.fi XMPP: sai...@retiisi.org.uk -- 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
