Merge tag 'for-linus-20131112' of git://git.infradead.org/linux-mtd
Pull MTD changes from Brian Norris: - Unify some compile-time differences so that we have fewer uses of #ifdef CONFIG_OF in atmel_nand - Other general cleanups (removing unused functions, options, variables, fields; use correct interfaces) - Fix BUG() for new odd-sized NAND, which report non-power-of-2 dimensions via ONFI - Miscellaneous driver fixes (SPI NOR flash; BCM47xx NAND flash; etc.) - Improve differentiation between SLC and MLC NAND -- this clarifies an ABI issue regarding the MTD "type" (in sysfs and in the MEMGETINFO ioctl), where the MTD_MLCNANDFLASH type was present but inconsistently used - Extend GPMI NAND to support multi-chip-select NAND for some platforms - Many improvements to the OMAP2/3 NAND driver, including an expanded DT binding to bring us closer to mainline support for some OMAP systems - Fix a deadlock in the error path of the Atmel NAND driver probe - Correct the error codes from MTD mmap() to conform to POSIX and the Linux Programmer's Manual. This is an acknowledged change in the MTD ABI, but I can't imagine somebody relying on the non-standard -ENOSYS error code specifically. Am I just being unimaginative? :) - Fix a few important GPMI NAND bugs (one regression from 3.12 and one long-standing race condition) - More?
