[PATCH 01/07] mfd: Add SuperH Mobile SDHI platform driver 
[PATCH 02/07] mmc: Add SuperH to the tmio-mmc Kconfig
[PATCH 03/07] mmc: Remove const from tmio-mmc platform data
[PATCH 04/07] sh: SDHI platform data to the Migo-R board

[PATCH 06/07] sh: SDHI platform data to the SE7724 board
[PATCH 07/07] sh: SDHI platform data to the kfr2r09 board

These patches contain the SuperH specific changes needed for
the tmio-mmc driver to work with SuperH Mobile SDHI hardware.

The tmio-mmc patch 0001-MMC-hardware-abstraction-for-CNF-area.patch
by Ian Molton is needed for correct run time behaviour. Without
this patch the tmio-mmc probe() fails gracefully.

I suggest merging the series in the SuperH tree. Not sure about
the best way to merge the patch by Ian.

[PATCH 01/07] mfd: Add SuperH Mobile SDHI platform driver

[Magnus Damm]

From: Magnus Damm <damm@opensource.se>

This patch adds an MFD driver for the SuperH Mobile SDHI
hardware block. At this point the driver simply wraps the
tmio-mmc driver with some clock code. In the future this
driver is the place to put SDHI specific hotplug code.

[PATCH 02/07] mmc: Add SuperH to the tmio-mmc Kconfig

[Magnus Damm]

From: Magnus Damm <damm@opensource.se>

Add SUPERH to the Kconfig dependencies for tmio_mmc.

This change allows us to drive the SDHI hardware blocks
found in SuperH Mobile with tmio_mmc.

Re: [PATCH 00/07] sh: SuperH Mobile SDHI changes

[Ian Molton]

I'm ok with the superH patches now. Those that depend on my patchset
which will be waiting on ASIC3 (my patchset needs to support ASIC3 to
avoid breaking already merged drivers).

Andrew: am I passing MMC patches via you?

At least patch 3/7 depends on Ian's patch being merged first, so there's
little point in merging this series until that hits upstream. So I'll
hold off on this for now.

yup.

I can't locate 0001-MMC-hardware-abstraction-for-CNF-area.patch
anywhere so I can't help with this merge.
