linux-next: manual merge of the arm-soc tree with the l2-mtd tree

Hi all,

Today's linux-next merge of the arm-soc tree got a conflict in
Documentation/devicetree/bindings/mtd/gpmc-nand.txt between commits
6c88058ef927 ("ARM: OMAP2+: cleaned-up DT support of various ECC
schemes") and 212012138deb ("mtd: nand: omap2: updated support for BCH4
ECC scheme") from the l2-mtd tree and commit 496c8a0bbb72 ("ARM: OMAP2+:
Allow NAND transfer mode to be specified in DT") from the arm-soc tree.

I fixed it up (maybe - see below) and can carry the fix as necessary (no
action is required).
