Hi,
I'm running linux-next on a tegra-sdhci host which has a Toshiba
THGBM2G6D2FBAI9 eMMC connected. During boot I get a "mmc1: power class
selection to bus width 8 failed" warning.
/sys/kernel/debug/mmc1# cat ios
clock: 48000000 Hz
actual clock: 48000000 Hz
vdd: 20 (3.2 ~ 3.3 V)
bus mode: 2 (push-pull)
chip select: 0 (don't care)
power mode: 2 (on)
bus width: 3 (8 bits)
timing spec: 1 (mmc high-speed)
Any hints?
Thanks!
Marc
