2012-06-26Revert "mmc: omap_hsmmc: Enable Auto CMD12"Ming Lei
This patch reverts the commit dba3c29ea4a1d5d544. After bisecting, this commit dba3c29 is found to ruin micro-SD card data (writing incorrect file, or fs is corrupt after several times mount) on the beagle-xm revB, and reverting the commit will fix the problem. Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about the Auto CMD12 Enable bit. - SDIO does not support this feature. - SD card only. Looks it is not suitable to always enable Auto CMD12 in host controller driver. Considered that the commit is not mature enough, so ask to revert it first.

2012-06-26mmc: block: fix the data timeout issue with ACMD22Subhash Jadavani
If multi block write operation fails for SD card, during error handling we send the SD_APP_SEND_NUM_WR_BLKS (ACMD22) to know how many blocks were already programmed by card. But mmc_sd_num_wr_blocks() function which sends the ACMD22 calculates the data timeout value from csd.tacc_ns and csd.tacc_clks parameters which will be 0 for block addressed (>2GB cards) SD card. This would result in timeout_ns and timeout_clks being 0 in the mmc_request passed to host driver. This means host controller would program its data timeout timer value with 0 which could result in DATA TIMEOUT errors from controller. To fix this issue, mmc_sd_num_wr_blocks() should instead just call the mmc_set_data_timeout() to calculate the data timeout value. mmc_set_data_timeout() function ensures that non zero timeout value is set even for block addressed SD cards.

If the GPIOs used by the MMCI driver are not registered yet when the driver is probe()d, they can't be used. This happens if the mmci driver is probed before the respective GPIO controller (e.g. on the LPC32xx EA3250 board, the PCA9532 GPIO controller would be initialized via DT after mmci). Therefore, we defer mmci in this case. Signed-off-by: Roland Stigge <stigge@antcom.de> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2012-06-06mmc: dw_mmc: fix the transmission handling in IDMACSeungwon Jeon
DTO interrupt can be later than transmit interrupt(IDMAC) in case of write. Current handling of IDMAC interrupt sets EVENT_DATA_COMPLETE as well as EVENT_XFER_COMPLETE regardless of DTO rising. This makes the current request finish in tasklet and permits the next request even though current data transfer is still in progress. As a result, sequence is broken and lock-up happens. Setting EVENT_DATA_COMPLETE is not proper after IDMAC interrupt. It should be taken after DTO interrupt is generated.

But currently, it first reads the register, second OR' 1b with SDIO_CCCR_IF[1], and then writes it back. As we can see, this is based on such assumption that the SDIO_CCCR_IF[0] is always 0.

2012-05-17mmc: omap: make it behave well as a moduleVenkatraman S
Use proper __devinit and __devexit annotation for driver functions. Instantiate the probe function for driver_ops instead of a probe in the register function. Signed-off-by: Venkatraman S <svenkatr@ti.com> Acked-by: Balaji T K <balajitk@ti.com> Signed-off-by: Chris Ball <cjb@laptop.org>
2012-05-17mmc: omap: convert to per instance workqueueVenkatraman S
Currently, a global mmc_omap_wq is created for all instances of omap hosts, which can lead to races and doesn't lend itself to unload the module cleanly. Instead, create per instance workqueue and remove the common workqueue.
