-The uSDHC supports DDR modes for eMMC devices running at 3.3V. This
-allows to run eMMC with 3.3V signaling voltage at DDR52 mode:
-
- # cat /sys/kernel/debug/mmc1/ios
- clock: 52000000 Hz
- vdd: 21 (3.3 ~ 3.4 V)
- bus mode: 2 (push-pull)
- chip select: 0 (don't care)
- power mode: 2 (on)
- bus width: 3 (8 bits)
- timing spec: 8 (mmc DDR52)
- signal voltage: 0 (3.30 V)
- driver type: 0 (driver type B)

-The field support_vsel is currently only used in the device tree
-case. Get rid of it. No change in behavior.
