2011-02-16workqueue, freezer: unify spelling of 'freeze' + 'able' to 'freezable'Tejun Heo1-1/+1
There are two spellings in use for 'freeze' + 'able' - 'freezable' and 'freezeable'. The former is the more prominent one. The latter is mostly used by workqueue and in a few other odd places. Unify the spelling to 'freezable'. Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: "Rafael J.

2010-10-25mtd: r852: remove useless pci powerup/down from suspend/resume routinesMaxim Levitsky1-29/+1
It turns out that pci core now handles these, so this code is redundant and can even cause bugs Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2010-06-02mtd/r852: update card detect early.Maxim Levitsky1-1/+1
This turns out to be the reason for DMA timeouts on resume, if card was inserted while system was suspended Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2010-06-02mtd/r852: Fixes in case of DMA timeoutMaxim Levitsky1-3/+11
* Don't call complete on dma completion * do a INIT_COMPLETE before using it each time * Report DMA read error via ecc 'correct' I finally managed to make my system do suspend to ram propertly, and I see that if card was inserted during suspend (while system was off), I get dma timeouts on resume. Simple card reinsert solves the issue. This patch solves a crash that would happen otherwise Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2010-06-02mtd/r852: register IRQ as last stepMaxim Levitsky1-5/+6
Otherwise, if it fires right away, it might access uninitialized spinlock Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2010-05-19mtd: update gfp/slab.h includesTejun Heo1-0/+1
Implicit slab.h inclusion via percpu.h is about to go away. Make sure gfp.h or slab.h is included as necessary. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2010-05-14mtd: sm_common: split smartmedia and xD tableMaxim Levitsky1-1/+1
2GB xD card, and 4MB SmartMedia ROM card share same ID, so to make both work split xD and smartmedia ID tables. Hardware driver must be able to know which type it handles (and probably just one).

2010-03-11mtd/nand/r852: Use pci_dma_mapping_error()David Woodhouse1-1/+1
... instead of comparing with DMA_ERROR_CODE, which will only work on powerpc/sparc/x86. Reported-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
2010-03-11mtd/nand/r852: fix build for CONFIG_PCI disabledRandy Dunlap1-0/+1
r852 fails to build when CONFIG_PCI is not enabled since it uses pci_*() calls and is a PCI driver, so it should depend on PCI to prevent build errors. It should also #include <linux/pci.h>. drivers/mtd/nand/r852.c:1053: error: implicit declaration of function 'pci_prepare_to_sleep' drivers/mtd/nand/r852.c:1062: error: implicit declaration of function 'pci_back_from_sleep' Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2010-02-27mtd: r852 fix pci IDMaxim Levitsky1-1/+1
The PCI_DEVICE_ID_RICOH_R5C852 was missed in the edited commit, and on second thought I just open code it. This fixes compile error. Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2010-02-26mtd: nand: Add driver for Ricoh xD/SmartMedia readerMaxim Levitsky1-0/+1117
This adds a driver for Ricoh R5C852 xD card reader. This reader is a part of larger mulifunction chip and found at least in R5C832 Driver is complete, but bewere of the fact that some (probably only type M) xD cards are 'fake' which means that they have an on board CPU and expose emulated nand command set These cards don't even store the oob area on the flash, but generate it on the fly from something else. Thus they demand to have proper values written in the oob area, and therefore only useful with SmartMedia FTL.
