Fix up various trivial conflicts, largely due to changes in calling conventions for things like dmaengine_prep_slave_sg() (new inline wrapper to hide new parameter, clashing with rewrite of previously last parameter that used to be an 'append' flag, and is now a bitmap of 'unsigned long flags'). (Also some header file fallout - like so many merges this merge window - and silly conflicts with sparse fixes) * tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6: (120 commits) mtd: docg3 add protection against concurrency mtd: docg3 refactor cascade floors structure mtd: docg3 increase write/erase timeout mtd: docg3 fix inbound calculations mtd: nand: gpmi: fix function annotations mtd: phram: fix section mismatch for phram_setup mtd: unify initialization of erase_info->fail_addr mtd: support ONFI multi lun NAND mtd: sm_ftl: fix typo in major number. mtd: add device-tree support to spear_smi mtd: spear_smi: Remove default partition information from driver mtd: Add device-tree support to fsmc_nand mtd: fix section mismatch for doc_probe_device mtd: nand/fsmc: Remove sparse warnings and errors mtd: nand/fsmc: Add DMA support mtd: nand/fsmc: Access the NAND device word by word whenever possible mtd: nand/fsmc: Use dev_err to report error scenario mtd: nand/fsmc: Use devm routines mtd: nand/fsmc: Modify fsmc driver to accept nand timing parameters via platform mtd: fsmc_nand: add pm callbacks to support hibernation ...

| | | | | | | | | | | | | | | | | | | | | | This patch is part of a set which fixes unnecessary flash erase and write errors resulting from the MTD CFI driver turning off vpp while an erase is in progress. This patch ensures that only those flash operations which call ENABLE_VPP() can then call DISABLE_VPP(). Other operations should never call DISABLE_VPP().

| | | | | | | | | | | | | | | | | | | | | | In many places in drivers we verify for the zero length, but this is very inconsistent across drivers. This is obviously the right thing to do, though. This patch moves the check to the MTD API functions instead and removes a lot of duplication.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already verify that offset and length are within the MTD device size in the MTD API functions.

This patch only affects the following API's: 'mtd_erase()' 'mtd_point()' 'mtd_unpoint()' 'mtd_get_unmapped_area()' 'mtd_read()' 'mtd_write()' 'mtd_panic_write()' 'mtd_lock()' 'mtd_unlock()' 'mtd_is_locked()' 'mtd_block_isbad()' 'mtd_block_markbad()' This patch adds a bit of noise by removing too sparse empty lines, but this is not too bad.

| | | | | | | | | | | | | | | | | | | | | | | | | | The 'mtd_unpoint()' API function should be able to return an error code because it may fail if you specify incorrect offset. This patch changes this MTD API function and amends all the drivers correspondingly. Also return '-EOPNOTSUPP' from 'mtd_unpoint()' when the '->unpoint()' method is undefined. We do not really need this currently, but this just makes sense to be consistent with 'mtd_point()'.

| * mtd: add leading underscore to all mtd functionsArtem Bityutskiy2012-03-277-58/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* mtd: fix hang-up in cfi erase and read contentionTadashi Abe2011-05-253-9/+5Star
| | | | | | | | | | | | | | cfi erase command hangs up when erase and read contention occurs. If read runs at the same address as erase operation, read issues Erase-Suspend via get_chip() and the erase goes into sleep in wait queue. But in this case, read operation exits by time-out without waking it up. I think the other variants (0001, 0020 and lpddr) have the same problem too. Tested and verified the patch only on CFI-0002 flash, though.

In the same commit initialisation of cfi->sector_erase_cmd made in cfi_chip_setup() (file drivers/mtd/chips/cfi_probe.c), so the CFI chip has no problem: ... cfi->cfi_mode = CFI_MODE_CFI; cfi->sector_erase_cmd = CMD(0x30); ...
