This reads like description of Linux internals (runtime_resume), which shouldn't be in the DT.
What does this mean at the HW level? I'm sure we can find a better name for this, or another way of describing this.

Are these proeprties placed on the MMC controller node, or a sub-node representing the card/slot?
