      mmc: tegra: add support for Tegra124 · 67debea3
      由 Stephen Warren 提交于 
      Tegra124's MMC controller is very similar to earlier SoC generations,
and can be supported by the same driver.

However, there are some non-backwards-compatible HW differences, and
hence a new DT compatible value must be used to describe the HW. This
patch updates the driver to support that new compatible value.

That said, the HW differences are only relevant when enabling certain
high-performance transfer modes. Since the driver is currently very
simple and doesn't enable those modes, we don't actually need to address
any of these HW differences in the code yet, hence the simple nature of
this patch.

      mmc: tegra: convert to device tree support only · b37f9d98
      由 Joseph Lo 提交于 
      When compiling a kernel that supports only Tegra30 and not Tegra20,
the SDHCI driver will fail to compile since the of_match_device() failure
fallback code unconditinally references soc_data_tegra20, which is only
compiled in when Tegra20 support is enabled.

In Kernel 3.7, both Tegra20 and Tegra30 will only support booting using
device tree, Hence, there is never a need to fall back to using
soc_data_tegra20 if of_mach_device() fails. Instead, make this case an
error. This removes the reference to soc_data_tegra20, and hence solves
the compile failure.

      mmc: sdhci-tegra: Explicitly support Tegra30 · 3e44a1a7
      由 Stephen Warren 提交于 
      Tegra30 differs from Tegra20 in a number of ways. This patch implements a
minimal set of differences in order to get the Cardhu board's SD slot and
eMMC working. Given the diffs between the mainline sdhci-tegra.c and our
downstream versions, I expect we'll eventually need to add many more
differences, hence the seemingly heavy-weight addition of the soc_data
structure.

* Tegra30 doesn't need to override register access to SDHCI_HOST_VERSION or
  SDHCI_INT_ENABLE.

* Tegra30 needs quirk SDHCI_QUIRK_DATA_TIMEOUT_USES_SDCLK.

      mmc: sdhci: change sdhci-pltfm into a module · f0de8369
      由 Shawn Guo 提交于 
      There are a couple of problems left from the sdhci pltfm and OF
consolidation changes.

* When building more than one sdhci-pltfm based drivers in the same
  image, linker will give multiple definition error on the sdhci-pltfm
  helper functions.  For example right now, building sdhci-of-esdhc
  and sdhci-of-hlwd together is a valid combination from Kconfig view.

* With the current build method, there is error with building the
  drivers as module, but module installation fails with modprobe.

The patch fixes above problems by changing sdhci-pltfm into a module.
To avoid EXPORT_SYMBOL on so many big endian IO accessors, it moves
these accessors into sdhci-pltfm.h as the 'static inline' functions.
As a result, sdhci.h needs to be included in sdhci-pltfm.h, and in
turn can be removed from individual drivers which already include
sdhci-pltfm.h.

      mmc: sdhci: make sdhci-pltfm device drivers self registered · 85d6509d
      由 Shawn Guo 提交于 
      The patch turns the common stuff in sdhci-pltfm.c into functions, and
add device drivers their own .probe and .remove which in turn call
into the common functions, so that those sdhci-pltfm device drivers
register itself and keep all device specific things away from common
sdhci-pltfm file.
