Linus, One case that I do not see handled is support of hardware clock gating.
SD 3.0 has this as well as our v2.0 controller. What I think makes sense is (from discussion with Nico on the mailing list) a) add a quirk that the driver can set to indicate h/w support for clock gating is available b) add a new field to ios that indicates if hardware clock gating to be enabled / disabled c) clock gating is set to disabled until final speed negotiation during card detection after which it may be enabled. d) keep sdio clock gating OFF -- need this from our experience. I can try to add this to your patch if you like or perhaps you can do this in the next submission regards, Philip -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
