I was wondering if we could remove one of the CAPS for DDR voltage (MMC_CAP_1_8V_DDR and MMC_CAP_1_2V_DDR). Both 1.2 and 1.8v are defined in the JEDEC Standard No. 84-A441.

The sd 3.0 host controller only defines the option for 1.8v.  I cannot see a way to set 1.2v. 

If this makes sense I can prepare a patch.
