Pull MTD updates from Brian Norris: - Add me (Brian Norris) as an additional MTD maintainer (it'd be nice to get David's "ack" for this; I'm sure he approves, but he's been pretty silent lately) - Add Ezequiel Garcie as maintainer for the pxa3xx NAND driver - Last (?) round of pxa3xx improvements for supporting Armada 370/XP - Typical churn in driver boilerplate (OOM messages, printk()'s, devm_*, etc.) - Quad read mode support for SPI NOR driver (m25p80) - Update Davinci NAND driver to prepare for use on new platforms - Begin to kill off NAND_MAX_{PAGE,OOB}SIZE macros; more work is pending - Miscellaneous NAND device support (new IDs) - Add READ RETRY support for Micron MLC NAND - Support new GPMI NAND ECC layout device-tree binding - Avoid mapping stack/vmalloc() memory for GPMI NAND DMA * tag 'for-linus-20140127' of git://git.infradead.org/linux-mtd: (151 commits) mtd: gpmi: add sanity check when mapping DMA for read_buf/write_buf mtd: gpmi: allocate a proper buffer for non ECC read/write mtd: m25p80: Set rx_nbits for Quad SPI transfers mtd: m25p80: Enable Quad SPI read transfers for s25fl512s mtd: s3c2410: Merge plat/regs-nand.h into s3c2410.c mtd: mtdram: add missing 'const' mtd: m25p80: assign default read command mtd: nuc900_nand: remove redundant return value check of platform_get_resource() mtd: plat_nand: remove redundant return value check of platform_get_resource() mtd: nand: add Intel manufacturer ID mtd: nand: add SanDisk manufacturer ID mtd: nand: add support for Samsung K9LCG08U0B mtd: nand: pxa3xx: Add support for 2048 bytes page size devices mtd: m25p80: Use OPCODE_QUAD_READ_4B for 4-byte addressing mtd: nand: don't use {read,write}_buf for 8-bit transfers mtd: nand: use __packed shorthand mtd: nand: support Micron READ RETRY mtd: nand: add generic READ RETRY support mtd: nand: add ONFI vendor block for Micron mtd: nand: localize ECC failures per page ...
