Merge tag 'for-linus-3.5-20120601' of git://git.infradead.org/linux-mtd
Pull mtd update from David Woodhouse: - More robust parsing especially of xattr data in JFFS2 - Updates to mxc_nand and gpmi drivers to support new boards and device tree - Improve consistency of information about ECC strength in NAND devices - Clean up partition handling of plat_nand - Support NAND drivers without dedicated access to OOB area - BCH hardware ECC support for OMAP - Other fixes and cleanups, and a few new device IDs Fixed trivial conflict in drivers/mtd/nand/gpmi-nand/gpmi-nand.c due to added include files next to each other. * tag 'for-linus-3.5-20120601' of git://git.infradead.org/linux-mtd: (75 commits) mtd: mxc_nand: move ecc strengh setup before nand_scan_tail mtd: block2mtd: fix recursive call of mtd_writev mtd: gpmi-nand: define ecc.strength mtd: of_parts: fix breakage in Kconfig mtd: nand: fix scan_read_raw_oob mtd: docg3 fix in-middle of blocks reads mtd: cfi_cmdset_0002: Slight cleanup of fixup messages mtd: add fixup for S29NS512P NOR flash. jffs2: allow to complete xattr integrity check on first GC scan jffs2: allow to discriminate between recoverable and non-recoverable errors mtd: nand: omap: add support for hardware BCH ecc ARM: OMAP3: gpmc: add BCH ecc api and modes mtd: nand: check the return code of 'read_oob/read_oob_raw' mtd: nand: remove 'sndcmd' parameter of 'read_oob/read_oob_raw' mtd: m25p80: Add support for Winbond W25Q80BW jffs2: get rid of jffs2_sync_super jffs2: remove unnecessary GC pass on sync jffs2: remove unnecessary GC pass on umount jffs2: remove lock_super mtd: gpmi: add gpmi support for mx6q ...

1* Freescale General-Purpose Media Interface (GPMI)
2
3The GPMI nand controller provides an interface to control the
4NAND flash chips. We support only one NAND chip now.
5
6Required properties:
7 - compatible : should be "fsl,<chip>-gpmi-nand"
8 - reg : should contain registers location and length for gpmi and bch.
9 - reg-names: Should contain the reg names "gpmi-nand" and "bch"
10 - interrupts : The first is the DMA interrupt number for GPMI.
11 The second is the BCH interrupt number.
12 - interrupt-names : The interrupt names "gpmi-dma", "bch";
13 - fsl,gpmi-dma-channel : Should contain the dma channel it uses.
14
15The device tree may optionally contain sub-nodes describing partitions of the
16address space. See partition.txt for more detail.
17
18Examples:
19
20gpmi-nand@8000c000 {
21 compatible = "fsl,imx28-gpmi-nand";
22 #address-cells = <1>;
23 #size-cells = <1>;
24 reg = <0x8000c000 2000>, <0x8000a000 2000>;
25 reg-names = "gpmi-nand", "bch";
26 interrupts = <88>, <41>;
27 interrupt-names = "gpmi-dma", "bch";
28 fsl,gpmi-dma-channel = <4>;
