2013-12-08mmc: block: fix a bug of error handling in MMC driverKOBAYASHI Yoshitake
commit c8760069627ad3b0dbbea170f0c4c58b16e18d3d upstream. Current MMC driver doesn't handle generic error (bit19 of device status) in write sequence. As a result, write data gets lost when generic error occurs. For example, a generic error when updating a filesystem management information causes a loss of write data and corrupts the filesystem. In the worst case, the system will never boot. This patch includes the following functionality: 1. To enable error checking for the response of CMD12 and CMD13 in write command sequence 2. To retry write sequence when a generic error occurs Messages are added for v2 to show what occurs.

commit c1fa3426aa5c782724c97394303d52228206eda4 upstream. When a software timeout occurs, the transfer is not stopped. In DMA case, it causes DMA channel to be stuck because the transfer is still active causing following transfers to be queued but not computed.

2013-09-26mmc: tmio_mmc_dma: fix PIO fallback on SDHISergei Shtylyov
commit f936f9b67b7f8c2eae01dd303a0e90bd777c4679 upstream. I'm testing SH-Mobile SDHI driver in DMA mode with a new DMA controller using 'bonnie++' and getting DMA error after which the tmio_mmc_dma.c code falls back to PIO but all commands time out after that. It turned out that the fallback code calls tmio_mmc_enable_dma() with RX/TX channels already freed and pointers to them cleared, so that the function bails out early instead of clearing the DMA bit in the CTL_DMA_ENABLE register. The regression was introduced by commit 162f43e31c5a376ec16336e5d0ac973373d54c89 (mmc: tmio: fix a deadlock). Moving tmio_mmc_enable_dma() calls to the top of the PIO fallback code in tmio_mmc_start_dma_{rx|tx}() helps.

2013-05-26mmc: sdhci-esdhc-imx: fix multiblock reads on i.MX53Lucas Stach
The eSDHC controller on the i.MX53 needs an additional, non spec compliant CMD12 after a multiblock read with a predefined number of blocks. Otherwise the internal state machine won't go back to the idle state. This commit effectively reverts 5b6b0ad6 (mmc: sdhci-esdhc-imx: fix for mmc cards on i.MX5), which fixed part of the problem by making multiblock reads work, however this fix was not sufficient when multi- and singleblock reads got intermixed. This implements the recommended workaround (Freescale i.MX Reference Manual, section 29.6.8 "Multi-block Read") by manually sending a CMD12 with the RSPTYP bits cleared.

2013-05-26mmc: sdhci-esdhc-imx: Fix SDIO interruptsMartin Fuzzey
Currently SDIO interrupts do not work on i.MX53 and maybe others. This was observed with a Marvell 8787 based SDIO wifi adapter using the mwifiex driver and firmware from the Marvell git repository. The symptom was a timeout after firmware download. Observing the SDIO_DAT1 line showed that an interrupt was requested (level 0) but no interrupt was generated in software, the line stayed low until a timeout ocurred and the card was reset. There is a Freescale errata ENGcm11186 "eSDHC misses SDIO interrupt when CINT is disabled" The workaround suggested by this errata is already implemented and involves clearing and then setting the D3CD bit in the host control register [see esdhc_writel_le()] However, when esdhc_writeb_le() is later used to write to SDHCI_HOST_CONTROL it always resets the D3CD bit. To fix this simply add the D3CD bit to the set of bits not modified by esdhc_writeb_le(). Signed-off-by: Martin Fuzzey <mfuzzey@parkeon.com> Signed-off-by: Chris Ball <cjb@laptop.org>

2013-04-30mmc: sdhci-s3c: Fix operation on non-single image Samsung platformsMark Brown
Commit cc014f3 (mmc: sdhci-s3c: remove platform dependencies) changed the platform dependency in Kconfig to depend on SAMSUNG_SINGLE, meaning the driver was available only on single zImage Samsung platforms. This breaks platforms that haven't been converted such as S3C64xx. Revert that part of the change to fix. [arnd: CONFIG_SAMSUNG_SINGLE was actually introduced only for non-multiplatform configurations, but was subsequently removed, which means the driver was now broken both for single- and multi- platform. The dependency was there by accident anyway, so reverting this is still the correct solution] Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
