      i2c: Add i2c_board_info and i2c_new_device() · 9c1600ed
      David Brownell authored
      This provides partial support for new-style I2C driver binding.  It builds
      on "struct i2c_board_info" declarations that identify I2C devices on a given
      board.  This is needed on systems with I2C devices that can't be fully probed
      and/or autoconfigured, such as many embedded Linux configurations where the
      way a given I2C device is wired may affect how it must be used.
      
      There are two models for declaring such devices:
      
       * LATE -- using a public function i2c_new_device().  This lets modules
         declare I2C devices found *AFTER* a given I2C adapter becomes available.
         
         For example, a PCI card could create adapters giving access to utility
         chips on that card, and this would be used to associate those chips with
         those adapters.
      
       * EARLY -- from arch_initcall() level code, using a non-exported function
         i2c_register_board_info().  This copies the declarations *BEFORE* such
         an i2c_adapter becomes available, arranging that i2c_new_device() will
         be called later when i2c-core registers the relevant i2c_adapter.
      
         For example, arch/.../.../board-*.c files would declare the I2C devices
         along with their platform data, and I2C devices would behave much like
         PNPACPI devices.  (That is, both enumerate from board-specific tables.)
      
      To match the exported i2c_new_device(), the previously-private function
      i2c_unregister_device() is now exported.
      
      Pending later patches using these new APIs, this is effectively a NOP.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
