-The emmc2 interface on the bcm2711 supports DDR modes for eMMC devices
-running at 3.3V. This allows to run eMMC module with 3.3V signaling voltage
-at DDR52 mode on the Raspberry Pi 4 using a SD adapter:
-
- clock: 52000000 Hz
- actual clock: 50000000 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: 2 (4 bits)
- timing spec: 8 (mmc DDR52)
- signal voltage: 0 (3.30 V)
- driver type: 0 (driver type B)
