2012-03-27mtd: nand/fsmc: Modify fsmc driver to accept nand timing parameters via platformVipin Kumar
FSMC controllers provide registers to program the required timing values for attached NAND device. The timing values used until now are relaxed and should work for all devices. Although, for read/write performance improvements, the fsmc nand driver should accept nand timings as a platform data and program the timing parameters into fsmc registers accordingly. This patch implements this modification. Additionally, it programs the default timing parameters if these are not passed via platform data.

2012-03-27mtd: check for zero length in OTP functionsArtem Bityutskiy
This patch changes all the OTP functions like 'mtd_get_fact_prot_info()' and makes them return zero immediately if the input 'len' parameter is 0. This is not really needed currently, but most of the other functions do this, and it is just consistent to do the same in the OTP functions.

2012-03-27mtd: nand: write BBM to OOB even with flash-based BBTBrian Norris
Currently, the flash-based BBT implementation writes bad block data only to its flash-based table and not to the OOB marker area. Then, as new bad blocks are marked over time, the OOB markers become incomplete and the flash-based table becomes the only source of current bad block information. This becomes an obvious problem when, for example: * bootloader cannot read the flash-based BBT format * BBT is corrupted and the flash must be rescanned for bad blocks; we want to remember bad blocks that were marked from Linux So to keep the bad block markers in sync with the flash-based BBT, this patch changes the default so that we write bad block markers to the proper OOB area on each block in addition to flash-based BBT. Comments are updated, expanded, and/or relocated as necessary. The new flash-based BBT procedure for marking bad blocks: (1) erase the affected block, to allow OOB marker to be written cleanly (2) update in-memory BBT (3) write bad block marker to OOB area of affected block (4) update flash-based BBT Note that we retain the first error encountered in (3) or (4), finish the procedures, and dump the error in the end. This should handle power cuts gracefully enough. (1) and (2) are mostly harmless (note that (1) will not erase an already-recognized bad block). The OOB and BBT may be "out of sync" if we experience power loss bewteen (3) and (4), but we can reasonably expect that on next boot, subsequent I/O operations will discover that the block should be marked bad again, thus re-syncing the OOB and BBT. Note that this is a change from the previous default flash-based BBT behavior. If your system cannot support writing bad block markers to OOB, use the new NAND_BBT_NO_OOB_BBM option (in combination with NAND_BBT_USE_FLASH and NAND_BBT_NO_OOB).

2012-03-27mtd: add leading underscore to all mtd functionsArtem Bityutskiy
This patch renames all MTD functions by adding a "_" prefix: mtd->erase -> mtd->_erase mtd->read_oob -> mtd->_read_oob ... The reason is that we are re-working the MTD API and from now on it is an error to use MTD function pointers directly - we have a corresponding API call for every pointer. By adding a leading "_" we achieve the following: 1. Make sure we convert every direct pointer users 2. A leading "_" suggests that this interface is internal and it becomes less likely that people will use them directly 3. Make sure all the out-of-tree modules stop compiling and the owners spot the big API change and amend them.

2012-03-26dma-buf: add support for kernel cpu accessDaniel Vetter
Big differences to other contenders in the field (like ion) is that this also supports highmem, so we have to split up the cpu access from the kernel side into a prepare and a kmap step. Prepare is allowed to fail and should do everything required so that the kmap calls can succeed (like swapin/backing storage allocation, flushing, ...). More in-depth explanations will follow in the follow-up documentation patch. Changes in v2: - Clear up begin_cpu_access confusion noticed by Sumit Semwal. - Don't automatically fallback from the _atomic variants to the non-atomic variants. The _atomic callbacks are not allowed to sleep, so we want exporters to make this decision explicit. The function signatures are explicit, so simpler exporters can still use the same function for both. - Make the unmap functions optional. Simpler exporters with permanent mappings don't need to do anything at unmap time. Changes in v3: - Adjust the WARN_ON checks for the new ->ops functions as suggested by Rob Clark and Sumit Semwal. - Rebased on top of latest dma-buf-next git.

2012-03-25ARM: dma-mapping: convert ARCH_HAS_DMA_SET_COHERENT_MASK to kconfig symbolRob Herring
The only users of ARCH_HAS_DMA_SET_COHERENT_MASK are 2 ARM platforms: ixp4xx and pxa cm_x2xx. We've been getting lucky that the define is implicitly included before dma-mapping.h, but the removal of io.h broke things (c334bc1 ARM: make mach/io.h include optional). Since memory.h is the correct place, but no longer exists, convert the define to a kconfig entry.
