Let's also add: The only hard evidence for introducing MMC_CAP_POWER_OFF_CARD was the Marvell sd8686 wifi chip, which was believed to require external gpio manipulation which wasn't supported by some boards. After further investigation it was realized (and confirmed by Marvell folks) that sd8686 requirements can be fulfilled by changing the reset sequence itself, even if no external gpio is manipulated.

This is exactly how I planed to take this too, thanks.
