Richard's solution below is right. > 2430 did have a separate MMC denounce clock which is controllable at the PRCM level. This is the name you mention above (2430 name). I don't think 3430 provides the same control. A 32K clock is fed into the MMC block, but it is probably controlled locally in MMC block not through clock API at PRCM level. > > Maybe you just need an ifdef or is_cpu_ call. - Paul -- 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
