mmc: sh_mmcif: revision-specific CLK_CTRL2 handling

2013-08-25T04:10:18+00:00

Some newer MMCIF IP revisions contain a CE_CLK_CTRL2 register, that has to
be set for proper operation. Support for this feature is added in a way to
preserve the current behaviour by default, i.e. when it is not enabled
in platform data. Patch is based on work by Nobuyuki HIRAI.

mmc: sh_mmcif: revision-specific Command Completion Signal handling

2013-08-25T04:10:17+00:00

Some earlier MMCIF IP revisions contained Command Completion Signal
support, which has been dropped again in modern versions. Sopport for
this feature is added in a way to preserve the current behaviour by
default, i.e. when it is not enabled in platform data. Patch is based
on work by Nobuyuki HIRAI.

mmc: sh_mmcif: move header include from header into .c

2013-08-25T04:10:14+00:00

sh_dma.h isn't needed in sh_mmcif.h, move it into sh_mmcif.c.

mmc: sh_mmcif: Remove .set_pwr() callback from platform data

2013-08-25T03:58:08+00:00

The .set_pwr() callback isn't used anymore as all platforms register
GPIO-controlled regulators. Remove it.

mmc: sh_mmcif: Remove .down_pwr() callback from platform data

2013-08-25T03:58:07+00:00

The callback isn't used by the driver and isn't initialized by board
code. Remove it.

Merge branch 'next' of git://git.infradead.org/users/vkoul/slave-dma

2012-07-25T00:12:54+00:00

Pull slave-dmaengine update from Vinod Koul:
 "This time we have a new dmaengine driver from the tegra folks.  Also
  we have Guennadi's cleanup of sh drivers which incudes a library for
  sh drivers.  And the usual odd fixes in bunch of drivers and some nice
  cleanup of dw_dmac from Andy."

Fix up conflicts in drivers/mmc/host/sh_mmcif.c

mmc: sh_mmcif: support generic card-detection

2012-07-21T04:02:22+00:00

Extend the sh_mmcif driver to support GPIO card detection, provided by the
slot function module. The original .get_cd() platform callback is also
preserved for now.

mmc: sh_mmcif: remove unneeded struct sh_mmcif_dma, prepare to shdma conversion

2012-07-13T03:43:07+00:00

Now that all users have been updated to use the embedded in struct
sh_mmcif_plat_data DMA slave IDs, struct sh_mmcif_dma is no longer needed
and can be removed. This also makes preparation to the shdma base library
conversion easier.

a way, similar to SDHI and other sh_dma clients.
