Didn't Jisheng ask for sdhci2 being registered at mmc0?
Renaming the node labels will not help, but have you tried using an:
aliases {
mmc0 = &sdhci2;
mmc1 = &sdhci0;
mmc2 = &sdhci1;
};
node and set the platform_device's .id field with what you get
from of_alias_get_id(np, "mmc")?
@Chris, Ulf: Is there any generic alias, e.g. "sdhci", you prefer for
drivers/mmc so we can put it into sdhci_get_of_property()?
