[PATCH v4 0/5] Enable SPI flash support on da850-evm DT kernel

[PATCH v4 0/5] Enable SPI flash support on da850-evm DT kernel

[Manjunathappa, Prakash]

Patch enables support for m25p64 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.

Applies on top of linux_davinci/master tree:
git://gitorious.org/linux-davinci/linux-davinci.git

Since v3:
Minor nit, fix tabs and commit message of 2/5.

Since v2:
Fix compatible property DT naming convention.

Since v1:
Look for m25p64 instead of m25p80 flash chip and correct partition information.
Dropped below accepted patch:
"spi/davinci: fix module build error"
Considered below missed out patch:
spi/davinci: add DT binding documentation

Manjunathappa, Prakash (4):
  spi/davinci: no wildcards in DT compatible property
  ARM: davinci: da850: add SPI1 DT node
  ARM: davinci: da850: override SPI DT node device name
  ARM: davinci: da850-evm: add SPI flash support
