2011-10-26mmc: dw_mmc: modify DATA register offsetJaehoon Chung
In dw_mmc 2.40a spec, Data register's offset is changed. Before we used Data register offset 0x100. but if somebody uses a 2.40a controller, we must use 0x200 for Data register.

If the host has support for this feature, then the mmc core will notify the device by setting the POWER_OFF_NOTIFICATION byte in the extended csd register with a value of 1 (POWER_ON).

The host controller state is restored at runtime resume. For Medfield, the host controller's card detect mechanism is supplanted by an always-on GPIO which provides for card detect wake-up.

2011-10-26mmc: sdhci-tegra: Add 8-bit support to device tree binding.Stephen Warren
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. While we're at it, fix the binding documentation to refer to "SD/MMC" instead of "eSDHC", since that's the correct name; "eSDHC" was cut/paste from the Freescale binding docs.

2011-10-26mmc: msm_sdcc: Enable SDC host->clk only after setting the rate.Sahitya Tummala
For clocks that support rates which can be set (most clocks other than _pclk AHB clocks), a rate must be set using clk_set_rate() before the clock is enabled for the first time with clk_enable(). Subsequent calls to clk_enable() need not be preceded with the clk_set_rate() calls unless we wish to change the clock rate that is set previously. SDC host->clk is currently enabled without setting the clock rate even once. This patch fixes this, by ensuring that the clock rate for this clock is first set before enabling the clock.

This allows boards with non-standard sdio cards to fill the CIS/CCCR data. It is particularly important for old msm72k boards using wl1251. Also drop the obsolete embedded_sdio_data structure from the header as it was intended to surve a similiar purpose but was not implemented.

2011-10-26mmc: sdhi: Allow named IRQs to use specific handlersSimon Horman
Allow named IRQs to use corresponding specific handlers. If named IRQs are used, at least an "sdcard" IRQ has to be specified by the platform. If names are not used, an arbitrary number of IRQs can be provided by the platform, in which case the generic ISR will be used for each of them.

2011-10-26mmc: tmio: Provide separate interrupt handlersSimon Horman
Provide separate interrupt handlers which may be used by platforms where SDHI has three interrupt sources. This patch also removes the commented-out handling of CRC and other errors.

2011-10-26mmc: tmio: Cache interrupt masksSimon Horman
This avoids the need to look up the masks each time an interrupt is handled. As suggested by Guennadi. Cc: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Magnus Damm <magnus.damm@gmail.com> Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: Chris Ball <cjb@laptop.org>
2011-10-26mmc: Kconfig: remove i.MX individual SoC dependencySascha Hauer
The individual SoC dependency in Kconfig hardly scales anymore. Instead of having such a fine grained dependency just depend on ARCH_MXC and risk that the uninformed user has to look in the help text to figure out which driver is the correct one.

2011-10-26mmc: sdhci-esdhc-imx: Enable ADMA2Richard Zhu
Eanble the ADMA2 mode for freescale esdhc imx driver, tested on MX25 3DS board, MX51 BBG board and MX53 LOCO board. This patch is only used to enable the ADMA2 for MX51/53 platforms. MX25/35 can't support the ADMA2 mode, set BROKEN_ADMA quirk on MX25/35 platforms. The ADMA mode supported or not can be distinguished by bit 20 of the Capability Register (offset 0x40) in the FSL eSDHC module.
