The datasheet states that MMC3 has no PBIAS circuit so you have to interface it with 1.8V logic. I used a TXS0108 from TI as a level translator. Datasheet states "The TXS0108E device is a semi-buffered auto-direction-sensing voltage translator design is optimized for translation applications (e.g. MMC Card Interfaces) that require the system to start out in a low-speed open-drain mode and then switch to a higher speed push-pull mode." So no need for transceiver control with this IC. > > I am trying to get pm working on the overo, and I have a recipe for the > overo for v.2.6.29 (which still has some issues with mmc1) and I have > v2.6.31 latest kernel update recipe for overo that has both DSS2 and PM > integrated. Have you tested the USB host with 2.6.31 recipe yet? Definitely would like the recipe for the v2.6.31. I have tested DSS2 on 2.6.30-rc8 and either I have a user error(most likely) or it wasn't working. I attempted to backport PM but as my main concern was for MMC. I stopped after realizing it wasn't absolutely necessary to get the new mmc patches to compile. > > I can share it with you if you like. > > Best regards, > > Elvis > > John Sarman -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
