Ok, now I have some info about the architecture. Unfortunately, it is still not clear to me how the different interfaces will work together with the DVB API. What I'm trying to understand is: what the Siano devices are? They are a DVB demod, a memory card, a usb bridge, ..., so we need different interfaces because the chip has completely different functions inside? Or it is a bridge to DVB functions, where the bridge can use different buses? > And now back to SDIO.... > > True all SDIO related sources files are now updated (after these 3 patches), but since the build system (Kconfig & Makefile) and "smscore" component are yet to be updated, the SDIO interface driver can not be linked into the module. Yes. I've sent an email to Pierre to be sure about the better way for we handle it. After having his return, I'll do the adjustments at the building system to allow us to build it inside the tree. > The option to link and use the SDIO interface driver, will be available after those files will be updated (hope it'll happen shortly). > > > One question: Should I continue submit patches (I have them ready), or should I wait till the 3 previous submission will be reviewed and committed? Better to hold them for a while, until I get a better picture.
