To: linux-omap
The omap850 and omap730 use 16-bit registers instead of 32-bit, requiring
a modification of the register addresses in the mmc-omap driver. To
make this as portable as possible, I made the following changes:
* Moved register address offsets from drivers/mmc/host/omap.c to
drivers/mmc/host/omap.h
* Implemented a lookup table for 16-bit and 32-bit register offsets
* Added a reg_size field in the mmc_omap_host structure
* Added code in mmc_omap_probe() to populate the reg_size
field based on processor in use
* Added inline function to return the register offset based on
the register size and register name
* Modified mmc-omap driver to use the new inline function to call out
register names
This change should allow the omap7xx-series of processors to correctly
utilize the MMC driver.

All this could be probably done by making register definition an index and
shifting it left by one or two depending on CPU. No lookup table needed.

Did you test it? It does not work on 5910, see here:

Agreed, this solution is more complicated than it probably needs to be.

Ah, good point, I hadn't considered that. I'll rework my
implementation to do that and resubmit.

Not sure why it wouldn't work on the 5910. I tested it on my device,
and it works properly for me, but then I don't have an omap-based
device that uses 32-bit register definitions. I'm confused at the
post you have above though...Is that with my patch, or is that with
something else? It seems to reference the status of current git,
which I don't think this patch shouldn't be in.

To put it clear, current git does not work and it is unrelated to your patch.
If driver works for you with your patch, then either your MMC card or
controller in your SoC survives multiple init sequences or it has something
to do with clock settings or... You can find two more people confirming
this here: http://www.spinics.net/lists/linux-omap/msg09547.html
I'll probably need to find some time to read MMC spec.

The omap850 and omap730 use 16-bit registers instead of 32-bit, requiring
a modification of the register addresses in the mmc-omap driver. To resolve
this, a bit shift is performed on base register addresses, either by 1 or 2
bits depending on the CPU in use. This yields the correct registers for
each CPU.

This is a resubmit of a patch I sent in several months ago. Tony Lindgren merged
this into linux-omap's master and testing branches but has stated that he will not
merge it further as linux-mmc needs to approve this. There hasn't been any comments
raised on either of the linux-omap or linux-mmc mailing lists about problems. Due to
the unique nature of the omap7xx platform, this patch is required for MMC card access.
Is there any chance this can be included into the next -rc cycle, as it is a fix for
devices that have 16-bit registers?

ignore this, didn't read the message properly and thought it was the i2c

Can you please queue this patch too? Ben's comments in this thread
were for the i2c-omap, not for this MMC patch. We've had this patch
in the omap tree for testing for quite a while now.
The patch is also available in at:
https://patchwork.kernel.org/patch/83971/
with the direct link to the mbox being:
https://patchwork.kernel.org/patch/83971/mbox/
Regards,
Tony
