* | | | mmc: sdhci-msm: remove support for Qualcomm chipsetsSubhash Jadavani2016-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The upstream sdhci-msm driver has diverged, removing the upstream version to recreate our internal tree from msm-3.18 to msm-4.4.

* | | | mmc: core: Fix error handling of MMC_BLK_DATA_ERRSahitya Tummala2016-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid retrying using single block for read commands that fail with MMC_BLK_DATA_ERR. The single block read retry is needed only in case of a CRC error for which MMC_BLK_ECC_ERR will be set anyway by mmc_blk_err_check().

* | | | mmc: sdhci: Reset cmd err only for sbc commandsVenkat Gopalakrishnan2016-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The data complete interrupt is also used to indicate that a busy state has ended. Fix a race condition between sdhci_cmd_irq() that sets any cmd err and sdhci_data_irq() (received to indicate end of busy state) that clears cmd error. This can happen when a cmd err is set and finish tasklet is scheduled but sdhci_data_irq() executes before the tasklet. The cmd err status is critical for the tasklet handler to reset the controller's state machine. This should be cleared only when we have successfully processed a sbc command and are ready to submit the actual command next, not when there is an actual cmd err.

* mmc: remove bondage between REQ_META and reliable writeLuca Porzio2015-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | Anytime a write operation is performed with Reliable Write flag enabled, the eMMC device is enforced to bypass the cache and do a write to the underling NVM device by Jedec specification; this causes a performance penalty since write operations can't be optimized by the device cache. In our tests, we replayed a typical mobile daily trace pattern and found ~9% overall time reduction in trace replay by using this patch. Also the write ops within 4KB~64KB chunk size range get a 40~60% performance improvement by using the patch (as this range of write chunks are the ones affected by REQ_META). This patch has been discussed in the Mobile & Embedded Linux Storage Forum and it's the results of feedbacks from many people. We also checked with fsdevl and f2fs mailing list developers that this change in the usage of REQ_META is not affecting FS behavior and we got positive feedbacks.

* mmc: mmc: Improve reliability of mmc_select_hs400()Adrian Hunter2015-11-09
| | | | | | | | | | | | | | | | | | | | | | | mmc_select_hs400() calls __mmc_switch() which checks the switch is successful using CMD13 (SEND_STATUS). The problem is that it does that using the timing settings of the previous mode. That is prone to error, especially when switching from HS to HS400 because the timing parameters for HS mode are tighter than the timing parameters for HS400 mode. In the case when CMD13 polling is used (i.e. not MMC_CAP_WAIT_WHILE_BUSY) with the switch command, it must be assumed that using different modes on the card and host must work. However in the case when CMD13 polling is not used (i.e. MMC_CAP_WAIT_WHILE_BUSY) mmc_select_hs400() can be made more reliable by setting the host to the correct timing before sending CMD13. This patch does that.

* mmc: mmc: Fix HS setting in mmc_select_hs400()Adrian Hunter2015-11-09
| | | | | | | | | | | | | | | | | | | | | mmc_select_hs400() begins with the card and host in HS200 mode. Therefore, any commands sent to the card should use HS200 timing. It is incorrect to set the host to High Speed (HS) timing before sending the switch command. Doing so is unreliable because the timing parameters for HS mode are tighter than the timing parameters for HS200 mode. Thus the HS timings should be set only after the card has switched mode. However, it is not unreasonable first to reduce the frequency to the HS mode frequency, which should make the switch command and subsequent CMD13 commands more reliable. This patch does that.

* mmc: mmc: Improve reliability of mmc_select_hs200()Adrian Hunter2015-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently mmc_select_hs200() uses __mmc_switch() which checks the success of the switch to HS200 mode using CMD13 (SEND_STATUS). The problem is that it does that using the timing settings of legacy mode. That is prone to error, not least because the timing parameters for legacy mode are tighter than the timing parameters for HS200 mode. In the case when CMD13 polling is used (i.e. not MMC_CAP_WAIT_WHILE_BUSY) with the switch command, it must be assumed that using different modes on the card and host must work. However in the case when CMD13 polling is not used (i.e. MMC_CAP_WAIT_WHILE_BUSY) mmc_select_hs200() can be made more reliable by setting the host to the correct timing before sending CMD13. This patch does that. A complication is that the caller, mmc_select_timing(), will ignore a switch error (indicated by -EBADMSG), assume the old mode is valid and continue, so the old timing must be restored in that case.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | An spi_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Andrew F. Davis <afd@ti.com> Acked-by: Jonathan Cameron <jic23@kernel.org> Signed-off-by: Mark Brown <broonie@kernel.org>
* | | mmc: dw_mmc: fix the wrong setting for UHS-DDR50 modeJaehoon Chung2015-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When card is running with DDR mode, dwmmc needs to set DDR_REG bit at UHS_REG register. Before this patch, dwmmc controller doesn't consider this. If this patch is not applied, CRC or other error shoulds be occurred.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to DesignWare DoC file, CardThreshold bit should be bit[27:16]. So it's correct to use (0xFFF << 16), not (0x1FFF << 16).

* | | mmc: pwrseq: Use highest priority for eMMC restart handlerJavier Martinez Canillas2015-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pwrseq_emmc driver does a eMMC card reset before a system reboot to allow broken or limited ROM boot-loaders (that don't have an eMMC reset logic) to be able to read the second stage from the eMMC. But this has to be called before a system reboot handler and while most of them use the priority 128, there are other restart handlers (such as the syscon-reboot one) that use a higher priority. So, use the highest priority to make sure that the eMMC hw is reset before a system reboot.
