cs5536: define dma_sff_read_status() method

2009-05-08T22:45:10Z

commit 15da90b516e9da92cc1d90001e640fd6707d0e27 upstream. The driver somehow got merged with the initializer for the dma_sff_read_status() method missing which caused kernel panic on bootup. This should fix the kernel.org bug #13026... Signed-off-by: Sergei Shtylyov Reported-by: Arnd Hannemann Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Greg Kroah-Hartman

hpt366: fix HPT370 DMA timeouts

2009-04-27T17:37:01Z

upstream commit: c018f1ee5cf81e58b93d9e93a2ee39cad13dc1ac The big driver change in 2.4.19-rc1 introduced a regression for many HPT370[A] chips -- DMA stopped to work completely, only causing endless timeouts... The culprit has been identified (at last!): it turned to be the code resetting the DMA state machine before each transfer. Stop doing it now as this counter- measure has clearly caused more harm than good. This should fix the kernel.org bug #7703.

ide-atapi: start DMA after issuing a packet command

2009-04-27T17:36:54Z

upstream commit: 2eba08270990b99fb5429b76ee97184ddd272f7f Apparently¹, some ATAPI devices want to see the packet command first before enabling DMA otherwise they simply hang indefinitely. Reorder the two steps and start DMA only after having issued the command first.

ide: Fix code dealing with sleeping devices in do_ide_request()

2009-04-27T17:36:51Z

upstream commit: 9010941c5483a7a5bb1f7d97ee62491fb078bb51 Unfortunately, I missed a catch when reviewing the patch committed as 201bffa4. Here is the fix to the currently broken handling of sleeping devices. In particular, this is required to get the disk shock protection code working again.

ide: save the returned value of dma_map_sg

2009-03-13T20:16:13Z

dma_map_sg could return a value different to 'nents' argument of dma_map_sg so the ide stack needs to save it for the later usage (e.g. for_each_sg). The ide stack also needs to save the original sg_nents value for pci_unmap_sg. Signed-off-by: FUJITA Tomonori [bart: backport to Linus' tree] Signed-off-by: Bartlomiej Zolnierkiewicz

ide: add at91_ide driver

2009-03-05T15:10:58Z

This is IDE host driver for AT91 (SAM9, CAP9, AT572D940HF) Static Memory Controller with Compact Flash True IDE Mode logic. Driver have to switch 8/16 bit bus width when accessing Task Tile or Data Register. Moreover some extra things need to be done when setting PIO mode. Only PIO mode is used, hardware have no DMA support. If interrupt line is connected through GPIO extra quirk is needed to cope with fake interrupts.

ide-iops: fix odd-length ATAPI PIO transfers

2009-03-05T15:10:56Z

Commit 9567b349f7e7dd7e2483db99ee8e4a6fe0caca38 (ide: merge ->atapi_*put_bytes and ->ata_*put_data methods) introduced a regression WRT the odd-length ATAPI PIO transfers -- the final word didn't get written (causing command timeouts).
