2012-07-31mmc: core: Fix PowerOff Notify suspend/resumePavan Kunapuli
Modified the mmc_poweroff to resume before sending the poweroff notification command. In sleep mode only AWAKE and RESET commands are allowed, so before sending the poweroff notification command resume from sleep mode and then send the notification command. PowerOff Notify is tested on a Synopsis Designware Host Controller (eMMC 4.5). The suspend to RAM and resume works fine.

2012-07-31mmc: core: Add option to prevent eMMC sleep commandUlf Hansson
Host may now use MMC_CAP2_NO_SLEEP_CMD to disable the use of eMMC sleep/awake command. This option can be used when your platform has a buggy kernel crash dump software, which is supposed to store the dump on the eMMC, but is not able to wake up the eMMC from sleep state. In particular, failures have been seen with u-boot; even if it is fixed there, platforms will be slow to update their bootloader binaries.

This reverts commit caa6566d4fb8539d09276c1bcb818444af675624. MMC_PM_KEEP_POWER should be used only for sdio as power-on/off code is implemented only for sdio. This may also create regression in power.

Tegra sdmmc controllers support fixed sampling frequency tuning. Also, frequency tuning is used to find the ideal tap delay value which ensures reliable high speed data transfers. Added support for the same. In SDR50 mode, setting controller clk rate to 208MHz as lower clk rates result in CRC errors.

Adding SDHCI_QUIRK_NO_CALC_MAX_DISCARD_TO for not to calculate max_discard_to which is deviation in setting max_discard. For some host controllers, combination of 1) calculated non-zero value of max_discard_to and 2) erase_group_def not set can result into setting max_discard value to pref_erase in sectors which is very less, so it takes long time for erase. With this change host controller can specify to calculate max_discard_to and based on that max_discard value will be set. bug 930767 Change-Id: I2c64ef8a6821620f2a65c06e25d2af68e3554a75 Signed-off-by: Shridhar Rasal <srasal@nvidia.com> Reviewed-on: http://git-master/r/79839 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Sachin Nikam <snikam@nvidia.com>
