[PATCH 0/4] Enable SPI flash support on da850-evm DT kernel

[Manjunathappa, Prakash]

Patch enables support for m25p80 SPI flash support on
da850-EVM.

Testing information:
da850-evm comes with partitions specified in DT blob.
Able to mount/umount and create/delete files on filesystem partition.

Depends on below patch in spi-next branch of git://git.secretlab.ca/git/linux-2.6.git.
"spi/davinci: add OF support for the spi controller"

Applies on top of below patch under community review:

Are you sure there is a m25p80 part on these boards? On my board using
this patch I get:

m25p80 spi32766.0: found m25p64, expected m25p80

I can access the flash just fine though.

Thanks,
Sekhar

On my board also I see this warning. Also there is mistake in filesystem
partition information specified in this patch, will correct it in next
version of patch.

The series looks good to me except a minor comment I gave on 4/4. Patch
1/4 should be picked by Grant (ideally before v3.9-rc1). I will queue
rest of patches for v3.10.

Grant,
I could not find binding documentation changes submitted with above patch.
I checked in spi-next and linux-next.

It must have been missed then. It happens sometimes. Can someone submit
a fixup patch please?
