Subject[GIT PULL] MTD changes for 3.13
Hi Linus,

David Woodhouse has given me the go-ahead to send the MTD pull request
for 3.13. Please take these fixes.

I've noted the highlights, and there are a few bits that are worth a
review (minor amendments to ABI; I don't want to hide them, but I also
think they are justified and safe).


The following changes since commit d255c59aab2a3fdf0bb8a5db75e50d9c926c3bb9:

Merge tag 'for-linus-20131025' of git:// (2013-10-25 20:15:13 +0100)

mtd: gpmi: fix the NULL pointer (2013-11-12 10:17:57 -0800)

MTD merge for 3.13

* 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
* 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 ioctl(MEMGETINFO)), 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? Read the log!
