      i2c: Add SMBus alert support · b5527a77
      Jean Delvare authored
      SMBus alert support. The SMBus alert protocol allows several SMBus
      slave devices to share a single interrupt pin on the SMBus master,
      while still allowing the master to know which slave triggered the
      This is based on preliminary work by David Brownell. The key
      difference between David's implementation and mine is that his was
      part of i2c-core, while mine is split into a separate, standalone
      module named i2c-smbus. The i2c-smbus module is meant to include
      support for all SMBus extensions to the I2C protocol in the future.
      The benefit of this approach is a zero cost for I2C bus segments which
      do not need SMBus alert support. Where David's implementation
      increased the size of struct i2c_adapter by 7% (40 bytes on i386),
      mine doesn't touch it. Where David's implementation added over 150
      lines of code to i2c-core (+10%), mine doesn't touch it. The only
      change that touches all the users of the i2c subsystem is a new
      callback in struct i2c_driver (common to both implementations.) I seem
      to remember Trent was worried about the footprint of David'd
      implementation, hopefully mine addresses the issue.

      i2c: Improve smbus-protocol documentation · 1a31a88f
      David Brownell authored
      Improve the smbus-protocol documentation file somewhat:
       - Use the names of the SMBus protocol operations (from the 2.0
         specification), not made-up-for-Linux names.
       - Add the name of the call used to execute each operation ... and
         point out that there are mismatches, where functions execute
         different protocol operations than their names specify.
      The most confusing examples are that "Read Byte" isn't executed by
      i2c_smbus_read_byte(), and that "Write Byte" isn't executed by
      i2c_smbus_write_byte().  When coding, that's not as bad as it may
      seem; but that case would seem to be worth fixing.

      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!
