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.

mmc: add runtime PM handlers

2010-10-23T13:11:18+00:00

Add MMC runtime PM handlers, which call mmc_power_save_host
and mmc_power_restore_host in response to runtime_suspend and
runtime_resume events.

Runtime PM is still disabled by default, so this patch alone
has no immediate effect.

mmc: Fixes for Dual Data Rate (DDR) support

2010-10-23T13:11:16+00:00

The DDR support patch needs the following fixes:

- The block driver does not need to know about DDR, any more
  than it needs to know about bus width.
- Not only the card must be switched to DDR mode.  The host
  controller must also be configured, which is done through
  the 'set_ios()' function.
- Do not set the DDR mode state until after the switch command
  is successful.
- Setting block length is not supported in DDR mode.  Make that
  a core function and change the other place it is used (mmc_test)
  also.

mmc: make mmc_dev_to_card() macro public

2010-10-23T13:11:12+00:00

Conversion from struct device to struct mmc_card is used more than in one
place.  Due to this it's better to have public macro for such thing.
