2014-07-21mmc: tegra: use 1.8V quirk only on affected instancesStefan Agner
The 1.8V quirk also affected the internal eMMC which disabled newer modes such as SDR50, SDR104 and DDR50. This in turn lead to an out of spec usage since the clock was still 50MHz. By creating a no_1v8 field in the platform data we can now enable this work around on a per-instance basis. Hence we enable the quirk only on the controllers which are connected to the external SD-slots.
2013-04-23colibri_t20: mmc: sdhci: fix buildMarcel Ziswiler
Fix the following build issue introduced by commit 5cfcbc23d116927a7ae8d5b67baeacf2905b21f9 if neither CONFIG_MACH_APALIS_T30 nor CONFIG_MACH_COLIBRI_T30 is defined as in case of e.g. the Colibri T20: drivers/mmc/host/sdhci-tegra.c:951:2: error: expected expression before '.' token
2013-04-18apalis/colibri_t30: mmc: sdhci: hack to make newer cards workMarcel Ziswiler
SDR12, SDR25, SDR50, SDR104 and DDR50 all require 1.8V signalling which our current T30 designs can't do. Newer cards will fail as follows: Kingston 32GB microSDHC class 10 [ 69.000280] mmc1: error -84 whilst initialising SD card SanDisk Mobile Ultra 8GB microSDHC I [ 28.289174] mmc1: error -110 whilst initialising SD card This patch activates a quirk which signals our lack of 1.8V support.
2013-04-18mmc: sdhci: add quirk for lack of 1.8v supportDaniel Drake
The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v capable, and it truthfully reports so in its capabilities. This alternate voltage is used for driving new "UHS-I" SD cards at their full speed. However, what the controller doesn't know is that the motherboard physically doesn't have a 1.8v supply available. Add a quirk so that systems such as this one can override disable 1.8v support, adding support for UHS-I cards (by running them at 3.3v). This avoids a problem where the system would first try to run the card at 1.8v, fail, and then not be able to fully reset the card to retry at the normal 3.3v voltage. This is more appropriate than using the MISSING_CAPS quirk, which is intended for cases where the SDHCI controller is actually lying about its capabilities, and would force us to somehow override both caps words from another source.

2012-02-09mmc: sdhci: quirk for not calculate max_discard_toShridhar Rasal
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>
