We are using ARASAN sd controller IP, it can be configurated to use shared pins mode in SoC design. And it looks like it is a common requirement to save chip footprint by sharing data bus between multi-controllers. Just because Our SoCs are still on the way to opensource and mainline. Even our arch/arm/mach-xxx hasn't been merged yet. Our target is syncing our codes with mainline. So as a modification to sdhci common level, we just get upstream's opinion for local maintaining earlier. Anyway, this patch may be applied later after our others are ready. Or it can be now so that other SoC companies can use this feature. > > Regards, > >  Wolfram > > -- > Pengutronix e.K.              | Wolfram Sang        Â| > Industrial Linux Solutions         | http://www.pengutronix.de/ Â| > -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
