Yes, there's lots of variation. Node names are supposed to be generic for their class of device (e.g. ethernet, pci, usb, interrupt-controller, etc.). I'd be fine with "sd", but think "mmc" is more common. Either way, we should pick one moving forward. "sdhci" should not be used as that's a specific implementation. Rob
