mmc: remove MMC bus legacy suspend/resume method

2012-04-21T00:30:19+00:00

MMC bus is using legacy suspend/resume method, which is not compatible if
runtime pm callbacks are used. In this scenario, MMC bus suspend/resume
callbacks cannot be called when system entering S3. So change to use the
new defined dev_pm_ops for system sleeping mode.

Tested on AM335x Platform. Solves major issue/crash reported at

mmc: core: HS200 mode support for eMMC 4.5

2012-01-12T20:17:15+00:00

This patch adds the support of the HS200 bus speed for eMMC 4.5 devices.
The eMMC 4.5 devices have support for 200MHz bus speed. The function
prototype of the tuning function is modified to handle the tuning
command number which is different in sd and mmc case.

mmc: sdio: support SDIO UHS cards

2012-01-12T04:58:41+00:00

This patch adds support for sdio UHS cards per the version 3.0
spec.

UHS mode is only enabled for version 3.0 cards when both the
host and the controller support UHS modes.

1.8v signaling support is removed if both the card and the
host do not support UHS.  This is done to maintain
compatibility and some system/card combinations break when
1.8v signaling is enabled when the host does not support UHS.

mmc: Fix implicit use of stat.h header in associated files

2011-10-31T23:32:07+00:00

Once the implicit use of module.h is prevented, these files will
fail to find the stat.h header content.

Fix up the implicit usage expectations in advance of the cleanup.

mmc: Add export.h for EXPORT_SYMBOL/THIS_MODULE as required

2011-10-31T23:32:06+00:00

These two basic defines were everywhere, simply because module.h
was also everywhere.   But we are cleaning up the latter.  So make
the exporters actually call out their need for the include.

mmc: sd: report correct speed and capacity of uhs cards

2011-05-25T03:53:46+00:00

Since only UHS-I cards respond with S18A set in response to ACMD41,
we set the card as ultra-high-speed after successfull initialization.
We need to decide whether a card is SDXC based on the C_SIZE field
of CSDv2.0 register. According to Physical Layer spec v3.01, the
minimum value of C_SIZE for SDXC card is 00FFFFh.

Tested by Zhangfei Gao with a Toshiba uhs card and general hs card,
on mmp2 in SDMA mode.

mmc: Register debugfs dir before calling card probe function.

2011-01-09T04:52:26+00:00

This way, the probe function may register debugfs files if it wants to.
This fixes a bug with mmc_test where mmc_test_register_file_test() is
called before the card's debugfs dir exists, and so it fails.
