siimage: use ->pio_mode value to determine pair device speed

2010-01-19T09:52:35+00:00

Use the current PIO mode value instead of the physical maximum one
of the pair device on the port to determine PIO commmand timings used
for both devices on the port.

siimage: use ide_dma_test_irq() (take 2)

2009-06-15T16:52:57+00:00

Remove interrupt bit test (not trusted anyway) from siimage_io_dma_test_irq()
and siimage_mmio_dma_test_irq() -- this allows to replace the former function
with now identical ide_dma_test_irq()...

ide: IORDY handling fixes

2009-06-15T16:52:53+00:00

Add ide_pio_need_iordy() helper and convert host drivers to use it.

This fixes it8172, it8213, pdc202xx_old, piix, slc90e66 and siimage
host drivers to handle IORDY correctly.

ide: replace special_t typedef by IDE_SFLAG_* flags

2009-05-17T17:12:21+00:00

Replace:
- special_t typedef by IDE_SFLAG_* flags
- 'special_t special' ide_drive_t's field by 'u8 special_flags' one

There should be no functional changes caused by this patch.

ide: add ->dma_clear method and remove ->dma_timeout one

2009-03-31T18:15:19+00:00

All custom ->dma_timeout implementations call the generic one thus it is
possible to have only an optional method for resetting DMA engine instead:

* Add ->dma_clear method and convert hpt366, pdc202xx_old and sl82c105
  host drivers to use it.

* Always use ide_dma_timeout() in ide_dma_timeout_retry() and remove
 ->dma_timeout method.

* Make ide_dma_timeout() static.

There should be no functional changes caused by this patch.

ide: add ->dma_timer_expiry method and remove ->dma_exec_cmd one (v2)

2009-03-27T11:46:47+00:00

* Rename dma_timer_expiry() to ide_dma_sff_timer_expiry() and export it.

* Add ->dma_timer_expiry method and use it to set hwif->expiry for
  ATA_PROT_DMA protocol in do_rw_taskfile().

* Initialize ->dma_timer_expiry to ide_dma_sff_timer_expiry() for SFF hosts.

* Move setting hwif->expiry from ide_execute_command() to its users and drop
  'expiry' argument.

* Use ide_execute_command() instead of ->dma_exec_cmd in do_rw_taskfile().

* Remove ->dma_exec_cmd method and its implementations.

* Unexport ide_execute_command() and ide_dma_intr().

v2:
* Fix CONFIG_BLK_DEV_IDEDMA=n build (noticed by Randy Dunlap).

* Fix *dma_expiry naming (suggested by Sergei Shtylyov).

There should be no functional changes caused by this patch.

ide: fix ->init_chipset method to return 'int' value

2009-03-24T22:22:53+00:00

* Return 0 instead of dev->irq in ->init_chipset implementations.

* Fix ->init_chipset method to return 'int' value instead of
  'unsigned int' one.

This fixes ->init_chipset handling for host drivers (cs5530, hpt366
and pdc202xx_new) for which it is possible for this method to fail.
