      ahci_imx: add ahci sata support on imx platforms · 9e54eae2
      Richard Zhu authored
      imx6q contains one Synopsys AHCI SATA controller, But it can't share
      ahci_platform driver with other controllers because there are some
      misalignments of the generic AHCI controller - the bits definitions of
      the HBA registers, the Vendor Specific registers, the AHCI PHY clock
      and the AHCI signals adjustment window(GPR13 register).
      
       - CAP_SSS(bit20) of the HOST_CAP is writable, default value is '0',
         should be configured to be '1'
      
       - bit0 (only one AHCI SATA port on imx6q) of the HOST_PORTS_IMPL
         should be set to be '1'.(default 0)
      
       - One Vendor Specific register HOST_TIMER1MS(offset:0xe0) should be
         configured regarding to the frequency of AHB bus clock.
      
       - Configurations of the AHCI PHY clock, and the signal parameters of
         the GPR13
      
      Setup its own ahci sata driver, contained the imx6q specific
      initialized codes, re-use the generic ahci_platform driver, and keep
      the generic ahci_platform driver clean as much as possible.

      libata: identify and init ZPODD devices · afe75951
      Aaron Lu authored
      The ODD can be enabled for ZPODD if the following three conditions are
      satisfied:
      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
      PIO.
      
      v2:
        - enable only when needed IORDY
        - use dev_get_drvdata
      v3:
        - add missing clk_put() calls
        - use platform_get_irq()
        - fix resume code to avoid disabling IORDY on resume
      v4:
        - 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
      functions.
      
      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.
