Merge tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6 

Pull MTD changes from David Woodhouse:
 - Artem's cleanup of the MTD API continues apace.
 - Fixes and improvements for ST FSMC and SuperH FLCTL NAND, amongst
   others.
 - More work on DiskOnChip G3, new driver for DiskOnChip G4.
 - Clean up debug/warning printks in JFFS2 to use pr_<level>.

Fix up various trivial conflicts, largely due to changes in calling
conventions for things like dmaengine_prep_slave_sg() (new inline
wrapper to hide new parameter, clashing with rewrite of previously last
parameter that used to be an 'append' flag, and is now a bitmap of
'unsigned long flags').

(Also some header file fallout - like so many merges this merge window -
and silly conflicts with sparse fixes)

* FSMC NAND



Required properties:

- compatible : "st,spear600-fsmc-nand"

- reg : Address range of the mtd chip

- reg-names: Should contain the reg names "fsmc_regs" and "nand_data"

- st,ale-off : Chip specific offset to ALE

- st,cle-off : Chip specific offset to CLE



Optional properties:

- bank-width : Width (in bytes) of the device.  If not present, the width

  defaults to 1 byte

- nand-skip-bbtscan: Indicates the the BBT scanning should be skipped



Example:



	fsmc: flash@d1800000 {

		compatible = "st,spear600-fsmc-nand";

		#address-cells = <1>;

		#size-cells = <1>;

		reg = <0xd1800000 0x1000	/* FSMC Register */

		       0xd2000000 0x4000>;	/* NAND Base */

		reg-names = "fsmc_regs", "nand_data";

		st,ale-off = <0x20000>;

		st,cle-off = <0x10000>;



		bank-width = <1>;

		nand-skip-bbtscan;



		partition@0 {

			...

		};

* SPEAr SMI



Required properties:

- compatible : "st,spear600-smi"

- reg : Address range of the mtd chip

- #address-cells, #size-cells : Must be present if the device has sub-nodes

  representing partitions.

- interrupt-parent: Should be the phandle for the interrupt controller

  that services interrupts for this device

- interrupts: Should contain the STMMAC interrupts

- clock-rate : Functional clock rate of SMI in Hz



Optional properties:

- st,smi-fast-mode : Flash supports read in fast mode



Example:



	smi: flash@fc000000 {

		compatible = "st,spear600-smi";

		#address-cells = <1>;

		#size-cells = <1>;

		reg = <0xfc000000 0x1000>;

		interrupt-parent = <&vic1>;

		interrupts = <12>;

		clock-rate = <50000000>;	/* 50MHz */



		flash@f8000000 {

			st,smi-fast-mode;

			...

		};

	};
