Hi Shashidhar,
ok, now that the bus width switch error became fatal in recent kernels, the
problem started to became painful...
I added some debug printks to the mmc_switch function in mmc_ops.c:
[1.433253] sdhci: Secure Digital Host Controller Interface driver
[1.442993] sdhci: Copyrig

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.
