ide/ata: Add export.h for EXPORT_SYMBOL/THIS_MODULE where needed

2011-10-31T23:31:37+00:00

They were getting this implicitly by an include of module.h
from device.h -- but we are going to clean that up and break
that include chain, so include export.h explicitly now.

ide: add drive->dma_mode field

2010-01-19T09:42:01+00:00

Add dma_mode field to ide_drive_t matching dma_mode field used in
struct ata_device.

The validity of the field is restricted to ->dma_pio_mode method
only currently in IDE subsystem.

ide: don't enable IORDY at a probe time

2009-06-15T16:52:54+00:00

* Add 'unsigned long port_flags' field to ide_hwif_t.

* Add IDE_PFLAG_PROBING port flag and keep it set during probing.

* Fix ide_pio_need_iordy() to not enable IORDY at a probe time
  (IORDY may lead to controller lock up on certain controllers
   if the port is not occupied).

Loosely based on the recent libata's fix by Tejun, thanks to Alan
for the hint that IDE may also need it.

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: add support for CFA specified transfer modes (take 3)

2009-03-31T18:15:28+00:00

Add support for the CompactFlash specific PIO modes 5/6 and MWDMA modes 3/4.

Since there were no PIO5 capable hard drives produced and one would also need
66 MHz IDE clock to actually get the difference WRT the address setup timings
programmed, I decided to simply replace the old non-standard PIO mode 5 timings
with the CFA specified ones.

ide: move xfer mode tuning code to ide-xfer-mode.c

2009-03-24T22:22:46+00:00

* Move xfer mode tuning code to ide-xfer-mode.c.

* Add CONFIG_IDE_XFER_MODE config option to be selected by host drivers
  that support xfer mode tuning.

* Add CONFIG_IDE_XFER_MODE=n static inline versions of ide_set_pio()
  and ide_set_xfer_rate().

* Make IDE_TIMINGS and BLK_DEV_IDEDMA config options select IDE_XFER_MODE,
  also add explicit selects for few host drivers that need it.

* Build/link ide-xfer-mode.o and ide-pio-blacklist.o (it is needed only
  by ide-xfer-mode.o) only if CONFIG_IDE_XFER_MODE=y.
