2013-03-19mmc: tegra: use mmc_of_parse to get the support of standard MMC DT bindingsJoseph Lo
Updating the sdhci-tegra driver to use mmc_of_parse to support standard MMC DT bindings. Then we can remove the redundant code that already support in generic MMC core.

2013-03-06mmc: sdhci-tegra: add basic support for Tegra114Rhyland Klein
The mmc controller on Tegra114 platforms is basically compatible with the settings used for Tegra30. However there is a difference where we don't need the extra ENABLE_SDHCI_SPEC_300 quirk as Tegra114 hardware advertises v3.0 support already.

2013-03-06mmc: sdhci-tegra: cleanup ifdefsRhyland Klein
The structs wrapped with the SOC ifdefs are small enough where having them always there shouldn't be a big overhead. Removing the ifdefs also makes the code a little cleaner.

2013-02-24mmc: tegra: assume CONFIG_OF, remove platform dataStephen Warren
Tegra only supports, and always enables, device tree. Remove all ifdefs and runtime checks for DT support from the driver. Platform data is therefore no longer required.

The 8bit in the function name is misleading. When set, it will be used to set the bus width, regardless of whether 8bit or another bus width is requested, so change the function name to platform_bus_width.

2012-09-04mmc: tegra: convert to device tree support onlyJoseph Lo
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.

The previous patch which implemented a DT binding for sdhci-tegra did not allow all platform data fields to be initialized from DT. The following were missing: is_8bit: Implemented by this patch. pm_flags: Not implemented yet. There are no mainline users of this field. I'm not quite sure what it's for, and hence how to represent this in DT; the value ends up being assigned to host->mmc->pm_caps.

2011-07-20mmc: sdhci: change sdhci-pltfm into a moduleShawn Guo
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.
