      Grant Likely authored
      Add of_driver_match_device() helper function.  This function can be used
      by bus types to determine if a driver works with a device when using OF
      style matching.  If CONFIG_OF is unselected, then it is a nop.

      of/gpio: add default of_xlate function if device has a node pointer · 391c970c
      Anton Vorontsov authored
      Implement generic OF gpio hooks and thus make device-enabled GPIO chips
      (i.e.  the ones that have gpio_chip->dev specified) automatically attach
      to the OpenFirmware subsystem.  Which means that now we can handle I2C and
      SPI GPIO chips almost* transparently.
      
      * "Almost" because some chips still require platform data, and for these
        chips OF-glue is still needed, though with this change the glue will
        be much smaller.

      of/gpio: stop using device_node data pointer to find gpio_chip · 594fa265
      Grant Likely authored
      Currently the kernel uses the struct device_node.data pointer to resolve
      a struct gpio_chip pointer from a device tree node.  However, the .data
      member doesn't provide any type checking and there aren't any rules
      enforced on what it should be used for.  There's no guarantee that the
      data stored in it actually points to an gpio_chip pointer.
      
      Instead of relying on the .data pointer, this patch modifies the code
      to add a lookup function which scans through the registered gpio_chips
      and returns the gpio_chip that has a pointer to the specified
      device_node.

      of/gpio: Kill of_gpio_chip and add members directly to gpio_chip · a19e3da5
      Anton Vorontsov authored
      The OF gpio infrastructure is great for describing GPIO connections within
      the device tree.  However, using a GPIO binding still requires changes to
      the gpio controller just to add an of_gpio structure.  In most cases, the
      gpio controller doesn't actually need any special support and the simple
      OF gpio mapping function is more than sufficient.  Additional, the current
      scheme of using of_gpio_chip requires a convoluted scheme to maintain
      1:1 mappings between of_gpio_chip and gpio_chip instances.
      
      If the struct of_gpio_chip data members were moved into struct gpio_chip,
      then it would simplify the processing of OF gpio bindings, and it would
      make it trivial to use device tree OF connections on existing gpiolib
      controller drivers.
      
      This patch eliminates the of_gpio_chip structure and moves the relevant
      fields into struct gpio_chip (conditional on CONFIG_OF_GPIO).  This move
      simplifies the existing code and prepares for adding automatic device tree
      support to existing drivers.

      of/device: populate platform_device (of_device) resource table on allocation · ac80a51e
      Grant Likely authored
      When allocating a platform_device to represent an OF node, also allocate
      space for the resource table and populate it with IRQ and reg property
      information.  This change is in preparation for merging the
      of_platform_bus_type with the platform_bus_type so that existing
      platform_driver code can retrieve base addresses and IRQs data.
      
      Background: a previous commit removed struct of_device and made it a
      #define alias for platform_device.

      because powerpc and microblaze use different default data.

      of/irq: merge irq mapping code · 7dc2e113
      Grant Likely authored
      Merge common irq mapping code between PowerPC and Microblaze.
      
      This patch merges of_irq_find_parent(), of_irq_map_raw() and
      of_irq_map_one().  The functions are dependent on one another, so all
      three are merged in a single patch.  Other than cosmetic difference
      (ie. DBG() vs. pr_debug()), the implementations are identical.
      
      of_irq_to_resource() is also merged, but in this case the
      implementations are different.  This patch drops the microblaze version
      and uses the powerpc implementation unchanged.  The microblaze version
      essentially open-coded irq_of_parse_and_map() which it does not need
      to do.  Therefore the powerpc version is safe to adopt.

      of: kill struct of_device · b505ff5e
      Grant Likely authored
      Now that the device tree node pointer has been moved out of struct
      of_device and into the common struct device, there isn't anything
      unique about of_device anymore.  In fact, there isn't much need
      for a separate of_bus when all busses have access to OF style
      probing.
      
      arch/powerpc and arch/microblaze are moving away from using the of_bus
      and using the regular platform bus instead for mmio devices.  This
      patch makes of_device the same as platform_device as a stepping stone
      in migrating of_platform_drivers over to the platform bus.

      sparc/of: Move of_device fields into struct pdev_archdata · 1636f8ac
      Grant Likely authored
      This patch moves SPARC architecture specific data members out of
      struct of_device and into the pdev_archdata structure.  The reason
      for this change is to unify the struct of_device definition amongst
      all the architectures.  It also remvoes the .sysdata, .slot, .portid
      and .clock_freq properties because they aren't actually used by
      anything.
      
      A subsequent patch will replace struct of_device entirely with struct
      platform_device and the of_platform support code will share common
      routines with the platform bus (but the bus instances themselves can
      remain separate).
      
      This patch also adds 'struct resources *resource' and num_resources
      to match the fields defined in struct platform_device.  After this
      change, 'struct platform_device' can be used as a drop-in replacement
      for 'struct of_platform'.
      
      This change is in preparation for merging the of_platform_bus_type
      with the platform_bus_type.
