• 398432edd   i2c: make i2c_check_addr_validity() static ... Browse Code »

  After previous refactoring, there is only one user in the same file
  left. Make the function static now.

• c64ffff7a   i2c: core: Allow empty id_table in ACPI case as well ... Browse Code »

  For now empty ID table is not allowed with ACPI and prevents driver to
  be probed.

  Add a check to allow empty ID table.

  This introduces a helper i2c_acpi_match_device().

  Note, we rename some static function in i2c-core-acpi.c to distinguish
  with public API.

• 9c1600eda   i2c: Add i2c_board_info and i2c_new_device() ... Browse Code »

  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.
