i.MX28: Do data transfers via DMA in MMC driver

2012-03-29T05:56:42Z

This utilizes the newly introduced bounce buffers in the MMC layer. Signed-off-by: Marek Vasut Cc: Stefano Babic Cc: Andy Fleming Cc: Fabio Estevam

MMC: Implement generic bounce buffer

2012-03-29T05:56:39Z

This implements generic bounce buffer at the end of MMC command submission chain. Therefore if unaligned data are passed, they are copied. This stuff should be pushed down into the MMC subsystem to squash all places generating these unaligned data. Signed-off-by: Marek Vasut Cc: Andy Fleming

ATMEL: remove old atmel_mci driver

2012-03-13T11:06:42Z

All boards are using the gen_atmel_mci driver now, so no need to carry the old driver around. Signed-off-by: Sven Schnelle Signed-off-by: Andreas Bießmann

ATMEL: use generic mmc framework

2012-03-13T11:06:41Z

gen_atmel_mci works on AVR32 as well, so no need to use the legacy mmc driver. This also has the nice side effect of being able to use SDHC cards an those boards. Signed-off-by: Sven Schnelle Signed-off-by: Andreas Bießmann

mmc: make mmc_send_status() more reliable

2012-02-15T23:42:22Z

Align the card status polling with the Linux kernel and retry the command at least five times. Also some cards apparently mishandle the status bits, so make sure to check the card state too. Signed-off-by: Jan Kloetzke Cc: Andy Fleming

mmc: fix card busy polling

2012-02-15T23:42:22Z

A MMC/SD card may always go into the programming state (and hence be busy) after a block write. Therefore always check the card state, even after single block writes. On the other hand there is no need to check the card status after a read. Also make sure that errors during busy polling are propagated upwards. Signed-off-by: Jan Kloetzke Cc: Andy Fleming

Tegra: mmc: Fixed handling of interrupts in timeouts.

2012-02-15T23:42:22Z

We are seeing occasional timeouts in the Tegra mmc code when we are reading from external MMC cards. These don't seem to be detrimental if they are handled properly. This CL properly clears the "normal interrupt status register" (norintsts) in error conditions. If we don't do this, when we come back into mmc_send_cmd() the register will still contain status from the last transaction. Signed-off-by: Doug Anderson Signed-off-by: Tom Warren

omap_hsmmc: Wait for CMDI to be clear

2012-02-15T23:42:22Z

Before we can send a command we need both the DATI (command inhibit on mmc_dat line) bit and CMDI (command inhibit on mmc_cmd line) are clear. The previous behavior of only checking on DATI was insufficient on some cards and incorrect behavior in any case. This makes the code check for both bits being clear and makes the error print more clear as to what happened. DATI_CMDDIS is removed as it was unused elsewhere in the code and stood for 'DATI is set, cmds are disabled still'. Fix originally spotted by Peter Bigot. Tested-by: Peter A.
