      it821x: PIO mode setup fixes · 0e9b4e53
      Bartlomiej Zolnierkiewicz authored
      * limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
        to setup PIO5 by it821x_tuneproc() could result in incorrect PIO timings
        + incorrect base clock being set for controller in the passthrough mode
      * move code limiting max PIO according to the pair device capabilities from
        config_it821x_chipset_for_pio() to it821x_tuneproc() so the check is also
        applied for mode change requests coming through ->tuneproc and ->speedproc
      * set device speed in it821x_tuneproc()
      * in it821x_tune_chipset() call it821x_tuneproc() also if the controller is
        in the smart mode (so the check for pair device max PIO is done)
      * rename it821x_tuneproc() to it821x_tune_pio(), then add it821x_tuneproc()
        wrapper which does the max PIO mode check;  it worked by the pure luck
        previously, pio[4] and pio_want[4] arrays were used with index == 255
        so random PIO timings and base clock were set for the controller in the
        passthrough mode, thankfully PIO timings and base clock were corrected
        later by config_it821x_chipset_for_pio() call (but it was not called for
        PIO-only devices during resume and for user requested PIO autotuning)
      * remove config_it821x_chipset_for_pio() call from config_chipset_for_dma()
        as the driver sets ->autotune to 1 and ->tuneproc does the proper job now
      * convert the last user of config_it821x_chipset_for_pio() to use
        it821x_tuneproc(drive, 255) and remove no longer needed function
      While at it:

      Teach the driver's tuneproc() method to do PIO auto-runing properly since it
      treated 5 instead of 255 as auto-tune request, and also passed the mode limit
      of PIO5 to ide_get_best_pio_mode() despite supporting up to PIO4 only.
      While at it, also:
      - remove the driver's wrong claim about supporting SWDMA modes;
      - stop hooking ide_dma_timeout() method as the handler clearly doesn't fit for

      cmd64x: use interrupt status from MRDMODE register (take 2) · 66602c83
      Sergei Shtylyov authored
      Fold the parts of the ide_dma_end() methods identical to __ide_dma_end() into a
      mere call to it.
      Start using faster versions of the ide_dma_end() and ide_dma_test_irq() methods
      for the PCI0646U and newer chips that have the duplicate interrupt status bits
      in the I/O mapped MRDMODE register, determing what methods to use at the driver
      load time. Do some cleanup/renaming in the "old" ide_dma_test_irq() method too.

      cmd64x: procfs code fixes/cleanups (take 2) · 5826b318
      Sergei Shtylyov authored
      Fix several issues with the driver's procfs output:
      - when testing if channel is enabled, the code looks at the "simplex" bits, not
        at the real enable bits -- add #define for the primary channel enable bit;
      - UltraDMA modes 0, 1, 3 for slave drive reported incorrectly due to using the
        master drive's clock cycle resolution bit.
      While at it, also perform the following cleanups:
      - don't print extra newline before the first controller's dump;
      - correct the chipset names (from CMDxxx to PCI-xxx)
      - don't read from the registers which aren't used for dump;
      - better align the table column sizes;
      - rework UltraDMA mode dump code;
      - remove PIO mode dump code that has never been finished;
      - remove the duplicate interrupt status (the MRDMODE register bits mirror those
        those in the CFR and ARTTIM23 registers) and fold the dump into single line;
      - correct the style of the ?: operators...

      cmd64x: add/fix enablebits (take 2) · 7accbffd
      Sergei Shtylyov authored
      The IDE core looks at the wrong bit when checking if the secondary channel is
      enabled on PCI0646 -- CNTRL register bit 7 is read-ahead disable, bit 3 is the
      correct one.
      Starting with PCI0646U chip, the primary channel can also be enabled/disabled --
      so, add 'enablebits' initializers to each 'ide_pci_device_t' structure, handling
      the original PCI0646 via adding the init_setup() method and clearing the 'reg'
      field there if necessary...

      cmd64x: interrupt status fixes (take 2) · e51e2528
      Sergei Shtylyov authored
      The driver's ide_dma_test_irq() method was reading the MRDMODE register even on
      PCI0643/6 where it was write-only -- fix this by always reading the "backward-
      compatible" interrupt bits, renaming dma_alt_stat to irq_stat as the interrupt
      status bits are not coupled to DMA.
      In addition, wrong interrupt bit was tested/cleared for the primary channel --
      it's bit 2 in all the chip specs and the driver used bit 1... :-/

      cmd64x: fix multiword and remove single-word DMA support · 60e7a82f
      Sergei Shtylyov authored
      Fix the multiword DMA and drop the single-word DMA support (which nobody will
      miss, I think).  In order to do it, a number of changes was necessary:
      - rename program_drive_counts() to program_cycle_times(), pass to it cycle's
        total/active times instead of the clock counts, and convert them into the
        active/recovery clocks there instead of cmd64x_tune_pio() -- this causes
        quantize_timing() to also move;
      - contrarywise, move all the code handling the address setup timing into
        cmd64x_tune_pio(), so that setting MWDMA mode wouldn't change address setup;
      - remove from the speedproc() method the  bogus code pretending to set the DMA
        timings by twiddling bits in the BMIDE status register, handle setting MWDMA
        by just calling program_cycle_times(); while at it, improve the style of that
        whole switch statement;
      - stop fiddling with the DMA capable bits in the speedproc() method -- they do
        not enable DMA, and are properly dealt with by the dma_host_{on,off} methods;
      - don't set hwif->swdma_mask in the init_hwif() method anymore.
      In addition to those changes, do the following:
      - in cmd64x_tune_pio(), when writing to ARTTIM23 register preserve the interrupt
        status bit, eliminate local_irq_{save|restore}() around this code as there's
        *no* actual race with the interrupt handler, and move cmdprintk() to a more
        fitting place -- after ide_get_best_pio_mode() call;
      - make {arttim|drwtim}_regs arrays single-dimensional, indexed with drive->dn;
      - rename {setup|recovery}_counts[] into more fitting {setup|recovery}_values[];
      - in  the speedproc() method, get rid of the duplicate reads/writes from/to the
        UDIDETCRx registers and of the extra variable used to store the transfer mode
        value after filtering,  use another method of determining master/slave drive,
        and cleanup useless parens;
      - beautify cmdprintk() output here and there.
      While at it, remove meaningless comment about the driver being used only on
      UltraSPARC and long non-relevant RCS tag. :-)

      sl82c105: DMA support code cleanup (take 4) · 688a87d1
      Sergei Shtylyov authored
      Fold the now equivalent code in the ide_dma_check() method into a mere call to
      ide_use_dma().  Make config_for_dma() return non-zero if DMA mode has been set
      and call it from the ide_dma_check() method instead of ide_dma_on().
      Defer writing the DMA timings to the chip registers until DMA is really turned
      on (and do not enable IORDY for DMA).
      Remove unneeded code from the init_hwif() method, improve its overall looks.
      Rename the dma_start(), ide_dma_check(), and ide_dma_lostirq() methods, and
      also use more proper hwif->dma_command, fix printk() and comment in the latter
      one as well.  While at it, cleanup style in several places.

      sl82c105: rework PIO support (take 2) · e93df705
      Sergei Shtylyov authored
      Get rid of the 'pio_speed' member of 'ide_drive_t' that was only used by this
      driver by storing the PIO mode timings in the 'drive_data' instead -- this
      allows us to greatly  simplify the process of "reloading" of the chip's timing
      register and do it right in sl82c150_dma_off_quietly() and to get rid of two
      extra arguments to config_for_pio() -- which got renamed to sl82c105_tune_pio()
      and now returns a PIO mode selected, with ide_config_drive_speed() call moved
      into the tuneproc() method, now called sl82c105_tune_drive() with the code to
      set drive's 'io_32bit' and 'unmask' flags in its turn moved to its proper place
      in the init_hwif() method.
      Also, while at it, rename get_timing_sl82c105() into get_pio_timings() and get
      rid of the code in it clamping cycle counts to 32 which was both incorrect and
      never executed anyway...

      [ARM] mm 10: allow memory type to be specified with ioremap · 3603ab2b
      Russell King authored
      __ioremap() took a set of page table flags (specifically the cacheable
      and bufferable bits) to control the mapping type.  However, with
      the advent of ARMv6, this is far too limited.
      Replace the page table flags with a memory type index, so that the
      desired attributes can be selected from the mem_type table.
      Finally, to prevent silent miscompilation due to the differing
      arguments, rename the __ioremap() and __ioremap_pfn() functions.
