Daniel once suggested reusing vmmc, however we found CD pin requires
vmmc to be alwayes on.
If vmmc is dynamically power off, CD pin will be low, which indicating
card is inserted by mistake.
For example when no card inserted, CD pin will high -> host fail to
detect sd card -> vmmc disabled in set_ios -> host thought card
inserted -> irq happen -> host redetect card ->

Sorry that I haven't been able to follow up on why that doesn't work,
and what the real fix would be (if it's not this one). Every time I
see people discussing terms like CD, RESETn and PDn, I simply get lost
(and such discussion seems to originate only from Marvell).

Are these generic SD/MMC terms that I simply don't understand, or are
we talking Marvell specific terminology that I'm not alone in lacking
understanding of?

Thanks,
Daniel
