| | | | | | | | | | | | | | | | | | This reverts commit 2943ecf2ed32632473c06f1975db47a7aa98c10f. This should go through the SPI maintainer, it was my fault that it did not. Especially as it conflicts with other patches he has pending. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.

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.

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 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)...

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." ] Signed-off-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
| * | | | hpt366: HPT36x PCI clock detection fixSergei Shtylyov2007-02-071-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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...
