      libata: identify and init ZPODD devices · afe75951
      Aaron Lu authored
      The ODD can be enabled for ZPODD if the following three conditions are
      1 The ODD supports device attention;
      2 The platform can runtime power off the ODD through ACPI;
      3 The ODD is either slot type or drawer type.
      For such ODDs, zpodd_init is called and a new structure is allocated for
      it to store ZPODD related stuffs.
      And the zpodd_dev_enabled function is used to test if ZPODD is currently
      enabled for this ODD.
      A new config CONFIG_SATA_ZPODD is added to selectively build ZPODD code.

      ata: Add iMX pata support · e39c75cf
      Arnaud Patard (Rtp) authored
      Add basic support for pata on iMX. It has been tested only on imx51.
      SDMA support will probably be added later so this version supports only
        - enable only when needed IORDY
        - use dev_get_drvdata
        - add missing clk_put() calls
        - use platform_get_irq()
        - fix resume code to avoid disabling IORDY on resume
        - Remove EXPERIMENTAL and switch to depends on ARCH_MXC
        - Use devm_kzalloc()
        - make clock a must-have
        - Use only 1 ioremap

      libata-sff: make BMDMA optional · 9a7780c9
      Tejun Heo authored
      Make BMDMA optional depending on new config variable CONFIG_ATA_BMDMA.
      In Kconfig, drivers are grouped into five groups - non-SFF native, SFF
      w/ custom DMA interface, SFF w/ BMDMA, PIO-only SFF, and generic
      fallback / legacy ones.  Kconfig and Makefile are reorganized
      according to the groups and ordered alphabetically inside each group.
      ata_ioports.bmdma_addr and ata_port.bmdma_prd[_dma] are put into
      CONFIG_ATA_BMDMA, as are all bmdma related ops, variables and
      This increase the binary size slightly when BMDMA is enabled but on
      both native-only and PIO-only configurations the size is slightly
      reduced.  Either way, the size difference is insignificant.  This
      change is more meaningful to signify the separation between SFF and
      BMDMA and as a tool to verify the separation.

      libata: make PMP support optional · 88fcd562
      Tejun Heo authored
      Make PMP support optional by adding CONFIG_SATA_PMP and leaving out
      libata-pmp.c if it isn't set.  PMP helpers return constant values if
      PMP support is not enabled and PMP declarations alias non-PMP
      counterparts.  This makes the compiler to leave out PMP related part
      out and LLDs to use non-PMP counterparts automatically.

      libata: make SFF support optional · 127102ae
      Tejun Heo authored
      Now that SFF support is completely separated out from the core layer,
      it can be made optional.  Add CONFIG_ATA_SFF and let SFF drivers
      depend on it.  If CONFIG_ATA_SFF isn't set, all codes in libata-sff.c
      and data structures for SFF support are disabled.  This saves good
      number of bytes for small systems.

      libata-pmp: implement Port Multiplier support · 3af9a77a
      Tejun Heo authored
      Implement Port Multiplier support.  To support PMP, a LLDD has to
      supply ops->pmp_read() and pmp_write().  If non-null, ->pmp_attach and
      ->pmp_detach are called on PMP attach and detach, respectively.
      ->pmp_read/write() can be called while the port is frozen, so they
      must be implemented by polling.  This patch supplies several helpers
      to ease ->pmp_read/write() implementation.
      Also, irq_handler and error_handler must be PMP aware.  Most of PMP
      aware EH can be done by calling ata_pmp_do_eh() with appropriate
      methods.  PMP EH uses separate set of reset methods and this patch
      implements standard prereset, hardreset and postreset methods.
      This patch only implements PMP support.  The next patch will integrate
      PMP into the reset of libata and thus enable PMP support.

      AVR32 PATA driver · 7c9ef8e4
      Kristoffer Nyborg Gregertsen authored
      Updated and simplified driver. Use only register transfer timing for both
      data and register transfers. This gives poorer performance in PIO1 and 2,
      but should not be a problem in PIO3 and 4, correct me if I'm wrong :)
      The driver works very we'll but I still wonder about the interrupts. I have
      an interrupt line, that works nicely when POLLING flag is not set. The
      problem is the number of interrupts that eat away my CPU cycles.
      When using the POLLING flag there seem to be some interrupts that dosen't get
      cleared. Furthermore the device dosen't drive INTRQ high, it stays at 2.5 volts
      and generates a lot of interrupts due to ripple / noise. What to do?
