      Grant Likely 提交于
      Allow a fixed framebuffer address to be assigned to the framebuffer device
      instead of allocating the framebuffer from the consistent memory pool.

      Grant Likely 提交于
      Some custom implementations of the xilinx fb can use resolutions other
      than 640x480.  This patch allows the resolution to be specified in the
      device tree or the xilinx_platform_data structure.

      ide: add ide_set{_max}_pio() (take 4) · 26bcb879
      Bartlomiej Zolnierkiewicz 提交于
      * Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags
        and set them in ht6560, cmd640, cmd64x and sc1200 host drivers.
      
      * Add set_pio_mode_abuse() for checking if host driver has a non-standard
        ->tuneproc() implementation and use it in do_special().
      
      * Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find
        the maximum PIO mode supported by the host), also add ide_set_max_pio()
        wrapper for ide_set_pio() to use for auto-tuning.  Convert users of
        ->tuneproc to use ide_set{_max}_pio() where possible.  This leaves only
        do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as
        a direct users of ->tuneproc.
      
      * Remove no longer needed ide_get_best_pio_mode() calls and printk-s
        reporting PIO mode selected from ->tuneproc implementations.
      
      * Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const.
      
      * Remove stale comment from ide_config_drive_speed().
      
      v2:
      * Fix "ata_" prefix (Noticed by Jeff).
      
      v3:
      * Minor cleanups/fixups per Sergei's suggestions.
      
      v4:
      * Fix compile problem in drivers/ide/pci/cmd640.c
        (Noticed by Andrew Morton).
      
      * Improve some ->set_pio_mode comments.

      ide: mode limiting fixes for user requested speed changes · 7670df73
      Bartlomiej Zolnierkiewicz 提交于
      * Add an extra argument to ide_max_dma_mode() for passing requested transfer
        mode.  Use it as an upper limit when finding the best DMA for device/host.
      
      * Rename ide_max_dma_mode() to ide_find_dma_mode() and at the same time add
        ide_max_dma_mode() wrapper which passes XFER_UDMA_6 as a requested mode to
        ide_find_dma_mode().  Also add inline ide_find_dma_mode() version for
        CONFIG_BLK_DEV_IDEDMA=n case.
      
      * Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask()
        to avoid false warning from eighty_ninty_three().
      
      * Use ide_find_dma_mode() to limit the user requested transfer mode in
        ide_rate_filter().  Also limit the requested mode by host max PIO mode.
      
      
      Above changes make ide_rate_filter() to:
      
      * Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19
        and 0x25-0x39, values > 0x46 were already clipped down, same for values
        0x25-0x39 but iff UDMA was not supported by the host).
      
      * Clip desired transfer mode down if it is currently unsupported by IDE core
        (PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was
        not supported by the host).
      
      * Clip desired transfer mode down according to the host capabilities
        (UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren't,
        also ->atapi_dma flag was not respected).
      
      * Clip desired transfer mode down according to the device capabilities
        (except PIO modes for now which require mode work) - shouldn't be a
        problem since ide_set_xfer_rate() is called _after_ device has accepted
        given transfer mode.

      	Power down drive (calls _PS3 method and turns off power planes).
      Powering up:
      	Power up drive (calls _PS0 method if present and turns on power planes).
      	Call _STM passing info from _GTM (possibly modified), with ID data from
      	each drive.
      	Initialize the channel.
      	May modify the results of _GTF.
      	For each drive:
      		Call _GTF.
      		Execute task file (possibly modified).
      This patch adds the missed _PS0/_PS3 methods call.

      hpt366: MWDMA filter for SATA cards (take 2) · b4e44369
      Sergei Shtylyov 提交于
      The Marvell bridge chips used on HighPoint SATA cards do not seem to support
      the MWDMA modes (at least that could be seen in their so-called drivers :-),
      so the driver needs to account for this -- to achieve this:
      
      - add mdma_filter() method from the original patch by Bartlomiej Zolnierkiewicz
        with his consent;
      
      - install the method for all chips to only return empty mask if a SATA drive
        is detected on HPT372{AN]/374 chips...
