Merge tag 'for-linus-20121009' of git://git.infradead.org/mtd-2.6
Pull MTD updates from David Woodhouse: - Disable broken mtdchar mmap() on MMU systems - Additional ECC tests for NAND flash, and some test cleanups - New NAND and SPI chip support - Fixes/cleanup for SH FLCTL NAND controller driver - Improved hardware support for GPMI NAND controller - Conversions to device-tree support for various drivers - Removal of obsolete drivers (sbc8xxx, bcmring, etc.) - New LPC32xx drivers for MLC and SLC NAND - Further cleanup of NAND OOB/ECC handling - UAPI cleanup merge from David Howells (just moving files, since MTD headers were sorted out long ago to separate user-visible from kernel bits) * tag 'for-linus-20121009' of git://git.infradead.org/mtd-2.6: (168 commits) mtd: Disable mtdchar mmap on MMU systems UAPI: (Scripted) Disintegrate include/mtd mtd: nand: detect Samsung K9GBG08U0A, K9GAG08U0F ID mtd: nand: decode Hynix MLC, 6-byte ID length mtd: nand: increase max OOB size to 640 mtd: nand: add generic READ ID length calculation functions mtd: nand: split simple ID decode into its own function mtd: nand: split extended ID decoding into its own function mtd: nand: split BB marker options decoding into its own function mtd: nand: remove redundant ID read mtd: nand: remove unnecessary variable mtd: docg4: add missing HAS_IOMEM dependency mtd: gpmi: initialize the timing registers only one time mtd: gpmi: add EDO feature for imx6q mtd: gpmi: do not set the default values for the extra clocks mtd: gpmi: simplify the DLL setting code mtd: gpmi: add a new field for HW_GPMI_CTRL1 mtd: gpmi: do not get the clock frequency in gpmi_begin() mtd: gpmi: add a new field for HW_GPMI_TIMING1 mtd: add helpers to get the supportted ONFI timing mode ...
