mmc: sdhi: Add write16_hook

2011-07-20T21:20:57Z

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

2011-05-25T03:53:55Z

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

2011-01-09T04:52:30Z

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. Signed-off-by: Arnd Hannemann Signed-off-by: Chris Ball

mmc: tmio_mmc: implement a bounce buffer for unaligned DMA

2011-01-09T04:52:29Z

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

2010-10-28T22:29:16Z

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. Signed-off-by: Yusuke Goda Signed-off-by: Matt Fleming Acked-by: Magnus Damm Tested-by: Arnd Hannemann Signed-off-by: Samuel Ortiz

mmc: Allow the tmio_mmc mfd driver to specify get_cd handler

2010-10-28T22:29:08Z

Some controllers, supported by the tmio_mmc driver do not have the card detect pin of a slot connected, so that polling needs to be used and card detection is handled by other means. This patch exposes a get_cd hook for that purpose. Signed-off-by: Arnd Hannemann Signed-off-by: Samuel Ortiz

mmc: let MFD's provide supported Vdd card voltages to tmio_mmc

tmio: add a platform flag to disable card write-protection detection

2010-05-22T08:05:21Z

Write-protection status is not always available, e.g., micro-SD cards do not have a write-protection switch at all. This patch adds a flag to let platforms force tmio_mmc to consider the card writable. Signed-off-by: Guennadi Liakhovetski Acked-by: Ian Molton Signed-off-by: Paul Mundt

mmc: prepare tmio_mmc for passing of DMA configuration from the MFD cell

2010-05-22T07:51:18Z

After this patch, if the "dma" pointer in struct tmio_mmc_data is not NULL, it points to a struct, containing two tokens, that have to be passed to the dmaengine driver for channel configuration. Signed-off-by: Guennadi Liakhovetski Acked-by: Samuel Ortiz Signed-off-by: Paul Mundt

tmio_mmc: Remove const from platform data V3

2010-03-07T21:17:27Z

Remove const from the tmio-mmc platform data hclk V3. This change makes it possible to remove the type cast from the sh_mobile_sdhi driver which is using the clock framework to get the clock rate. Signed-off-by: Magnus Damm Signed-off-by: Samuel Ortiz
