This adds the module name to all PCI drivers, if they are built into the
kernel or not. It will show up in /sys/modules/MODULE_NAME/drivers/
It also fixes up the IDE core, which was calling __pci_register_driver()
directly.

This patch implements ACPI integration for generic IDE devices.
The ACPI spec mandates that some methods are called during suspend and
resume. And consequently there most modern Laptops cannot resume
properly without it.
According to the spec, we should call '_GTM' (Get Timing) upon suspend
to store the current IDE adapter settings.
Upon resume we should call '_STM' (Set Timing) to initialize the
adapter with the stored settings; afterwards '_GTF' (Get Taskfile)
should be called which returns a buffer with some IDE initialisation
commands. Those commands should be passed to the drive.
There are two module params which control the behaviour of this patch:
'ide=noacpi'
Do not call any ACPI methods (Disables any ACPI method calls)
'ide=acpigtf'
Enable execution of _GTF methods upon resume.
Has no effect if 'ide=noacpi' is set.
'ide=acpionboot'
Enable execution of ACPI methods during boot.
This might be required on some machines if 'ide=acpigtf' is
selected as some machines modify the _GTF information
depending on the drive identification passed down with _STM.

Bart, here's a driver I've been keeping out-of-tree for the past couple
of years. This is for the Delking/Lexar/ASKA/etc.. 32-bit cardbus IDE
CompactFlash adapter card.
It's probably way out of sync with the latest driver model (??), but it
still builds/works. I'm not interested in doing much of a rewrite, other
than for libata someday, as I no longer use the card myself.
But lots of other people do seem to use it, so it might be nice to see it
"in-tree".

This is the driver for the Toshiba TC86C001 GOKU-S PCI IDE controller,
completely reworked from the original brain-damaged Toshiba's 2.4 version.
This single channel UltraDMA/66 controller is very simple in programming,
yet Toshiba managed to plant many interesting bugs in it. The particularly
nasty "limitation 5" (as they call the errata) caused me to abuse the IDE
core in a possibly most interesting way so far. However, this is still
better than the #ifdef mess in drivers/ide/ide-io.c that the original
version included (well, it had much more mess)...

Remove the following useless fragments from the driver:
- the ide_dma_lostirq() and ide_dma_timeout() handlers which boil down to just
printing the incoherent reset message and calling their default counterparts;
- check for non-NULL drive->id in the ide_dma_check() handler -- this is assumed
to be true by all other handlers (also, get rid of unnecessary nesting of the
conditional statements there);
- the comment before pdcnew_tune_drive() which has nothing to do with the code.

- carry over Alan's and my own fixes in the tuneproc() method and my cleanups
both there and in the ratemask() method;
- SLC90E66 only supports MW DMA modes 1/2 and SW DMA mode 2 (just like Intel
chips), so don't claim support for other MW/SW DMA modes;
- don't check dor non-NULL drive->id in the ide_dma_check() method -- this is
assumed to be true in all other drivers;
- do some coding/formatting cleanups while at it...

Fix/cleanup the driver's tuneproc() and ratemask() methods:
- PPE, IE, and TIME bits need to be cleared beforehand for the slave drive as
well as master (Alan probably just forgot about it);
- this driver only supports PIO modes up to 4, so must pass the correct limit
to ide_get_best_pio_mode();
- use min_t() macro instead of min();
- simplify slave vs master drive evaluation;
- do come coding and formatting cleanups...

According to the datasheet, Intel 82371MX (MPIIX) actually has only a
single IDE channel mapped to the primary or secondary ports depending on
the value of the bit 14 of the IDETIM register at PCI config. offset 0x6C
(the register at 0x6F which the driver refers to. doesn't exist). So,
disguise the controller as dual channel and set enablebits masks/values
such that only either primary or secondary channel is detected enabled.
Also, preclude the IDE probing code from reading PCI BARs, this controller
just doesn't have them (it's not the separate PCI function like the other
PCI controllers), it only decodes the legacy addresses.
[ Alan sayeth " MPIIX does not work with or without the change. It needs its
own different driver and not to use setup-pci. Huge job and since it works
well with libata who cares. Ditto the early PIIX chip." ]

Fix minor coding mistake in the HPT36x PCI clock detection code noticed by
Bartlomiej Zolnierkiewicz -- it always reported 33 MHz due to the missing
'break' statements. This, however, most probably never mattered -- in fact, I
was thinking of removing the 25/40 MHz cases completely since HPT36x BIOSes
didn't seem to set any other value than 7 into the 'cmd_high_time' field, i.e.
supported only 33 MHz PCI.
Note that in the original driver there was another bug: 25 and 40 MHz cases
were interchanged. Since the 'cmd_high_time' field is in units of PCI clocks,
a lower clock count just *cannot* correspond to a higher frequency, i. e. it
should be 5 for 25 MHz PCI and 9 for 40 MHz PCI, not the other way around.

Finally, rework the driver init. code to correctly handle all the chip
variants HighPoint has created so far. This should cure the rest of the
timing issues in the driver (especially, on 66 MHz PCI) caused by the
HighPoint's habit of switching the base DPLL clock with every new revision
of the chips...
- switch to using the enumeration type to differ between the numerous chip
variants, matching PCI device/revision ID with the chip type early, at the
init_setup stage;
- extend the hpt_info structure to hold the DPLL and PCI clock frequencies,
stop duplicating it for each channel by storing the pointer in the pci_dev
structure: first, at the init_setup stage, point it to a static "template"
with only the chip type and its specific base DPLL frequency, the highest
supported DMA mode, and the chip settings table pointer filled, then, at
the init_chipset stage, allocate per-chip instance and fill it with the
rest of the necessary information;
- get rid of the constant thresholds in the HPT37x PCI clock detection code,
switch to calculating PCI clock frequency based on the chip's base DPLL
frequency;
- switch to using the DPLL clock and enable UltraATA/133 mode by default on
anything newer than HPT370/A;
- fold PCI clock detection and DPLL setup code into init_chipset_hpt366(),
unify the HPT36x/37x setup code and the speedproc handlers by joining the
register setting lists into the table indexed by the clock selected;
- add enablebits for all the chips to avoid touching disabled channels
(though the HighPoint BIOS seem to only disable the primary one on
HPT371/N);
- separate the UltraDMA and MWDMA masks there to avoid changing PIO timings
when setting an UltraDMA mode in hpt37x_tune_chipset().
This version has been tested on HPT370/302/371N.
Thanks to Alan for the inspiration. Hopefully, his libata driver will also
benefit from the work done on this "obsolete" driver...

Clean up DMA timeout handling for HPT370:
- hpt370_lostirq_timeout() cleared the DMA status which made __ide_dma_end()
called afterwards return the incorrect result, and the DMA engine was reset
both before and after stopping DMA while the HighPoint drivers only do it
after (which seems logical) -- fix this and also rename the function;
- get rid of the needless mutual recursion in hpt370_ide_dma_end() and
hpt370_ide_dma_timeout();
- get rid of hpt370_lostirq_timeout() since hwif->ide_dma_end() called from
the driver's interrupt handler later does all its work.

Continue with the driver rewrite:
- move the interrupt twiddling code from the speedproc handlers into the
init_hwif_hpt366 which allows to merge the two HPT37x speedproc handlers
into one;
- get rid of in init_hpt366 which solely consists of the duplicate code, then
fold init_hpt37x() into init_chipset_hpt366();
- fix hpt3xx_tune_drive() to always set the PIO mode requested, not the best
possible one, change hpt366_config_drive_xfer_rate() accordingly, simplify
it a bit;
- group all the DMA related code together init_hwif_hpt366(), and generally
clean up and beautify it.

Begin the real driver redesign. For the starters:
- cache the offset of the IDE channel's MISC. control registers which are used
throughout the driver in hwif->select_data;
- only touch the relevant MCR when detecting the cable type on HPT374's
function 1;
- make HPT36x's speedproc handler look the same way as HPT37x ones; fix the
PIO timing register mask for HPT37x.
- rename all the HPT3xx register related variables consistently; clean up the
whitespace.

Switch to using pci_get_slot() to get to the function 1 of HPT36x/374 chips --

- Rework the driver setup code so that it prefixes the driver startup
messages with the real chip name.
- Print the measured f_CNT value and the DPLL setting for non-HPT3xx
chips as well.

those having PCI device ID of 0x0004.

- Rework hpt3xx_ratemask() and hpt3xx_ratefilter() so that the former
returns the max. mode computed at the load time and doesn't have to do
bad Ultra33 drive list lookups anymore; remove the duplicate code from
the latter function. Move the quirky drive list lookup into
hpt3xx_quirkproc() where it should have been from the start...
- Disable UltraATA/100 for HPT370 by default as the 33 MHz ATA clock
being used does not allow for it, and this *greatly* increases the
transfer speed.
- Save some space by using byte-wide fields in struct hpt_info; switch to
reading the 8-bit PCI revision ID reg. only, not the whole 32-bit reg.
- Start incrementing the driver version number with each patch (should
have been done from the first one posted).

This patch fixes 2.6.15 regression, is straightforward and tested.
Cable detection got broken probably while converting the driver to support
multiple controllers. Cable detection is done by examining how BIOS
configured the attached devices. The current code is broken in that it
examines the status *after* modifying Clk66 configuration ending up
detecting 40c cables as 80c. This patch fixes it.

The fallback to PIO mode in the hwif->dma_check() handler doesn't work in
the Intel PIIX and SMsC SLC90E66 IDE drivers because:
- config_drive_for_dma() calls the hwif->speedproc() handler with a wrong
mode number (unbiased by XFER_PIO_0) in case of the PIO fallback;
- hwif->tuneproc() handler doesn't really set the drive's own speed (this
is not fixed as yet).

There's no need to check in piix_config_drive_for_dma() for broken MW DMA
mode 0 as this mode is not supported by the driver (it sets
hwif->mwdma_mask to 0x6), and hence can't be selected by ide_dma_speed().
(Alan sayeth "Probably right but if not you've got a subtle corruptor. Should
at least stick a BUG_ON mode 0 setting right close when the mode is set.")

The undocumented register BIOS uses for saving f_CNT seems to only be
mapped to I/O space while all the other HPT3xx regs are dual-mapped. Looks
like another HighPoint's dirty trick. With this patch, the deadly kernel
oops on the cards having the modern HighPoint BIOSes is now at last gone!

Use the f_CNT value saved by the HighPoint BIOS if available as reading it
directly would give us a wrong PCI frequency after DPLL has already been
calibrated by BIOS.

init_chipset_hpt366() modifies some fields of the ide_pci_device_t structure
depending on the chip's revision, so pass it a copy of the structure to avoid
issues when multiple different chips are present.

Fix the broken hotswap code: on HPT37x it caused RESET- to glitch when
tristating the bus (the MISC control 3/6 and soft control 2 need to be written
to in the certain order), and for HPT36x the obsolete HDIO_TRISTATE_HWIF
ioctl() handler was called instead which treated the state argument wrong.
Also, get rid of the soft control reg. 1 wtite to enable IDE interrupt --
this is done in init_hpt37x() already...
Have been tested on HPT370 and 371N.

Save some space on the timing tables by introducing the separate transfer mode
table in which the mode lookup is done to get the index into the timing table
itself. Get rid of the rest of the obsolete/duplicate tables and use one set
of tables for the whole HPT37x chip family like the HighPoint open-source
drivers do. Documnent the different timing register layout for the HPT36x
chip family (this is my guesswork based on the timing values).
Have been tested and works fine on HPT370/302/371N.

Fix/remove bad/unused timing tables: HPT370/A 66 MHz tables weren't really
needed (the chips are not UltraATA/133 capable and shouldn't support 66 MHz
PCI) and had many modes over- and underclocked, HPT372 33 MHz table was in
fact for 66 MHz and 50 MHz table missed UltraDMA mode 6, HPT374 33 MHz table
was really for 50 MHz... (Actually, HPT370/A 33 MHz tables also have issues.
e.g. HPT370 has PIO modes 0/1 overlocked.)
There's also no need in the separate HPT374 tables because HPT372 timings
should be the same (and those tables has UltraDMA mode 6 which HPT374 supports
depending on HPT374_ALLOW_ATA133_6 #define)...

Fix serious problems with the HPT372N clock turnaround code:
- the wrong ports were written to when called for the secondary channel;
- it didn't serialize access to the channels;
- turnaround shou;dn't be done on 66 MHz PCI;
- caching the clock mode per-channel caused it to get out of sync with the
actual register value.
Additionally, avoid calibrating PLL twice (for each channel) as the second try
results in a wrong PCI frequency and thus in the wrong timings.
Make the driver deal with HPT302N and HPT371N correctly -- the clocking and
(seemingly) a need for clock tunaround is the same as for HPT372N. HPT371/N
chips have only one, secondary channel, so avoid touching their "pure virtual"
primary channel, and disable it if the BIOS haven't done this already.
Also, while at it, disable UltraATA/133 for HPT372 by default -- 50 MHz DPLL
clock don't allow for this speed anyway. And remove the traces of the former
bad patch that wasn't even applicable to this version of driver.
Has been tested on HPT370/371N, unfortunately I don't have an instant access
to the other chips...
