Hello Simon,

do you remember reason why you chose that CONFIG_DM_MMC should not depend on CONFIG_MMC?

[PATCH] dm: mmc: Add an MMC uclass e7ecf7cb5a6b873daf2d88daf03034d51fad4acc

My gut feeling is that it should have that dependency like DM_USB depends on USB and DM_PCI depends PCI.

The same question arises for DM_SCSI, DM_SERIAL where such a dependency is also missing.

Furthermore shouldn't DM_MMC default to MMC && DM?

We cannot express this in Kconfig yet due to USB gadget stuff, iirc. I think we had this discussion and root-causing over on imx6 maybe 2 months ago? Thanks!
