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.

mmc: tmio_mmc: implement a bounce buffer for unaligned DMA

2011-01-09T04:52:29+00:00

For example, with SDIO WLAN cards, some transfers happen with buffers at
odd addresses, whereas the SH-Mobile DMA engine requires even addresses
for SDHI. This patch extends the tmio driver with a bounce buffer, that
is used for single entry scatter-gather lists both for sending and
receiving. If we ever encounter unaligned transfers with multi-element
sg lists, this patch will have to be extended. For now it just falls
back to PIO in this and other unsupported cases.

mmc: Allow 2 byte requests in 4-bit mode for tmio_mmc

2010-10-28T22:29:16+00:00

Adjust the tmio_mmc block size check to accept 2-byte requests in 4-bit
mode if the hardware supports it.

Tested with the SDHI hardware block included in sh7724.
