    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
