This is my patch to improve error recovery.
Note that in MMC mode, if a command fails as indicated by cmd->error
being non-zero, that means we didn't get a valid response from the
card, which in turn means that cmd->resp[] is invalid, and all other
state should be ignored. (The way we set things

Ahh, I see we're talking about a removable SD card. In that case,

The driver looks like it is for the same block (or very close

For one, this is needed for power-management. In powered suspend case,

Hello,
Maybe a stupid question, but when designing new hardware with a slot
for an sd-card, how essential is it that the driver is able to power off/on
the card?
I would say essential, because I've seen sd-cards in a state in which they
didn't respond to MMC_GO_IDLE_STATE anymore, until they were

On a larger scale, we try to go in the opposite direction: make it possible

Can you sum up the differences why you cannot sdhci.c directly, please?

This patch adds support a new sdmmc controller which name is
'Mobile Storage Host Controller'. Its base version is 2.30a.
The 'mshci.c' is based on 'linux/drivers/mmc/host/sdhci.c' and
the role is exactly same with that.
NOTE:
This patch covers 1bit, 4bit and 8bit bus width
