mmc: sdhi/tmio: switch to using dmaengine_slave_config()

2013-05-26T18:23:20+00:00

This removes the deprecated use of the .private member of struct dma_chan
and switches the sdhi / tmio mmc driver to using the
dmaengine_slave_config() channel configuration method.

mmc: sdhi/tmio: make DMA filter implementation specific

2013-05-26T18:23:19+00:00

So far only the SDHI implementation uses TMIO MMC with DMA. That way a DMA
channel filter function, defined in the TMIO driver wasn't a problem.
However, such a filter function is DMA controller specific. Since the SDHI
glue is only running on systems with the SHDMA DMA controller, the filter
function can safely be provided by it. Move it into SDHI.

mmc: tmio: remove unused and deprecated symbols

2013-02-24T19:37:24+00:00

The tmio_mmc_cd_wakeup() inline function has been deprecated since 3.4 and
is unused since 3.4 too. Remove them.

mmc: tmio: support caps2 flags

2012-07-21T04:02:18+00:00

Allow tmio mmc glue drivers to pass mmc_host::caps2 flags down to
the mmc layer.

mmc: tmio: add callbacks to enable-update and disable the interface clock

2012-07-21T04:02:10+00:00

Every time the clock is enabled after possibly being disabled, we have
to re-read its frequency and update our configuration.

mmc: tmio_mmc: power status flag doesn't have to be exposed in platform data

2012-03-27T16:20:16+00:00

The controller power status flag does not have to be accessed from the
hot-plug detection code any more, it can now be removed from the platform
data and put in the controller private struct.

mmc: tmio_mmc: support the generic MMC GPIO card hotplug helper

2012-03-27T16:20:15+00:00

If the platform specifies the TMIO_MMC_HAS_COLD_CD flag, use the generic
MMC GPIO card hotplug helper.

mmc: sdhi: Add write16_hook

2011-07-20T21:20:57+00:00

Some controllers require waiting for the bus to become idle
before writing to some registers. I have implemented this
by adding a hook to sd_ctrl_write16() and implementing
a hook for SDHI which waits for the bus to become idle.

mmc: tmio: runtime suspend the controller, where possible

2011-05-25T03:53:55+00:00

The TMIO MMC controller cannot be powered off to save power, when no
card is plugged in, because then it will not be able to detect a new
card-insertion event. On some implementations, however, it is
possible to switch to using another source to detect card insertion.
This patch adds support for such implementations.

mmc: tmio_mmc: implement SDIO IRQ support

2011-01-09T04:52:30+00:00

This patch implements SDIO IRQ support for mfds which
announce the TMIO_MMC_SDIO_IRQ flag for tmio_mmc.
If MMC_CAP_SDIO_IRQ is also set SDIO IRQ signalling is activated.
Tested with a b43-based wireless SDIO card and sh_mobile_sdhi.
