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) Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> |
