Subject: [PATCH 0/3] mtd: s3c2410: add device tree support

This series adds support for configuring Samsung's s3c2410 and
compatible flash memory controller via devicetree.

Tested on FriendlyARM mini2440, based on s3c2440 SoC.

Patch 3 depends on patch 1.

Changes since v1:
- read timings from nand_sdr_timings when booting with a device tree
- naming improvements in the device tree binding
  (s/nand/nand-controller/, s/_/-, s/children/child)
- dropped property samsung,ignore_unset_ecc
- remove @0 from nand device node
- checking pdev->dev.of_node instead of using ifdef CONFIG_OF_MTD
- preventing from parsing device tree properties twice
- increment the nand controller child node refcount, since we
  maintain a reference to it and its name field
- using of_device_get_match_data() instead of of_match_device()
  to make the code simpler
- remove CONFIG_MTD_NAND_S3C2410_HWECC compile option so we can
  select ECC mode using nand-ecc-mode property in the device tree

Sergio Prado (3):
  mtd: s3c2410: make ecc mode configurable via platform data
  dt-bindings: mtd: add DT binding for s3c2410 flash controller
  mtd: s3c2410: parse the device configuration from OF node
