mmc: tmio: convert the SDHI MMC driver from MFD to a platform driver

2011-03-25T14:39:23+00:00

On sh-mobile platforms the SDHI driver was using the tmio_mmc SD/SDIO MFD cell driver. Now that the tmio_mmc driver has been split into a core and a separate MFD glue, we can support SDHI natively without the need to emulate an MFD controller. This also allows to support systems with an on-SoC SDHI controller and a separate MFD with a TMIO core. Signed-off-by: Guennadi Liakhovetski Acked-by: Paul Mundt Signed-off-by: Chris Ball

mmc: Use mfd_data instead of driver_data for tmio-mmc

2011-03-23T09:41:56+00:00

Use mfd_data for passing information from mfd drivers to mfd clients. The mfd_cell's driver_data field is being phased out. Clients that were using driver_data now access .mfd_data via mfd_get_data(). This changes tmio-mmc only; mfd drivers with other cells are not modified.

mfd: mfd_cell is now implicitly available to sh_mobile_sdhi drivers

2011-03-23T09:41:53+00:00

No need to explicitly set the cell's platform_data/data_size. Signed-off-by: Andres Salomon Signed-off-by: Samuel Ortiz

mfd: sh_mobile_sdhi: activate SDIO IRQ for tmio_mmc

2011-01-09T04:52:31+00:00

The SDHI Controller on SH-Mobile SoCs supports SDIO IRQ signalling. This patch advertises this fact to the tmio_mmc driver. Signed-off-by: Arnd Hannemann Acked-by: Samuel Ortiz Signed-off-by: Chris Ball

mfd: sdhi: require the tmio-mmc driver to bounce unaligned buffers

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

The SDHI controller on SH-Mobile SoCs requires even buffer addresses, when used with DMA. Signed-off-by: Guennadi Liakhovetski Acked-by: Samuel Ortiz Signed-off-by: Chris Ball

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

mfd: Allow the platform to specify the sh_mobile_sdhi get_cd handler

2010-10-28T22:29:11+00:00

On some platforms (e.g. AP4EVB) the card detect pin of a slot is not directly connected to the sdhi hardware, so that polling needs to be used with tmio_mmc and card detection is handled in the platform code. This patch allows to set tmio_mmc capabilities (to pass the MMC_CAP_NEEDS_POLL flag) and exposes a get_cd hook for that purpose. Signed-off-by: Arnd Hannemann Signed-off-by: Samuel Ortiz

mfd: Fix up section mismatches in SH SDHI.

2010-09-16T08:14:40+00:00

The current probe/remove definitions are split between __init and __devexit, make them consistent by switching to __devinit. Signed-off-by: Paul Mundt

sh: allow platforms to specify SD-card supported voltages

2010-05-22T08:05:22+00:00

Boards can have different supplied voltages on different SD card slots. This information has to be passed down to the SD/MMC driver. Signed-off-by: Guennadi Liakhovetski Acked-by: Ian Molton Signed-off-by: Paul Mundt
