2008-01-23libata: implement ata_timing_cycle2mode() and use it in libata-acpi and ↵Tejun Heo
pata_acpi libata-acpi is using separate timing tables for transfer modes although libata-core has the complete ata_timing table. Implement ata_timing_cycle2mode() to look for matching mode given transfer type and cycle duration and use it in libata-acpi and pata_acpi to replace private timing tables.

2008-01-23libata: separate out ata_acpi_gtm_xfermask() from pacpi_discover_modes()Tejun Heo
Finding out matching transfer mode from ACPI GTM values is useful for other purposes too. Separate out the function and timing tables from pata_acpi::pacpi_discover_modes(). Other than checking shared-configuration bit after doing ata_acpi_gtm() in pacpi_discover_modes() which should be safe, this patch doesn't introduce any behavior change.

2007-10-17pata_acpi: fix build breakage if !CONFIG_PMTejun Heo
There are configurations where CONFIG_ACPI but !CONFIG_PM. In this case, pata_acpi can be selected but won't build. Fix it. Reported by Avuton Olrich. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Avuton Olrich <avuton@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-10-12pata_acpi: ACPI driver supportAlan Cox
On a cable there may be eighty wires or perhaps forty and we learn about its type In the world of ACPI So we call the GTM And we find the the timing rate And we look through it to see If eighty wire it must be Timing lives in ACPI routines ACPI routines, ACPI routines Timing lives in ACPI routines ACPI routes ACPI routines And the drivers last you see Picking up unknown pci ids and the code begins to work Timing lives in ACPI routines ACPI routines, ACPI routines Timing lives in ACPI routines ACPI routes ACPI routines [Full speed ahead, Mr Hacker, full speed ahead] Full speed over here sir! Checking Cable, checking cable Aye aye, 80 wire, Heaven heaven] If we use ACPI (ACPI) Every box (every box) has all we need (has all we need) Cable type (cable type) and mode timing (mode timing) In our ATA (in our ATA) subroutines (subroutines, ha ha) Timing lives in ACPI routines ACPI routines, ACPI routines Timing lives in ACPI routines ACPI routes ACPI routines Timing lives in ACPI routines ACPI routines, ACPI routines Timing lives in ACPI routines ACPI routes ACPI routines Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
