Subject: [PATCH v6 0/6] fsi: Add IBM I2C Responder virtual FSI master

The I2C Responder (I2CR) is an I2C device that translates I2C commands
to CFAM or SCOM operations, effectively implementing an FSI master and
bus.

Changes since v5:
 - Make I2CR scom driver depend on I2CR FSI master

Changes since v4:
 - Add I2CR scom driver and associated patches
 - Use compatible strings for FSI drivers if specified
 - Include aliased device numbering patch
 - Restructure the trace events to eliminate holes

Changes since v3:
 - Rework the endian-ness in i2cr_write
 - Rework the tracing to include the i2c bus and device address

Changes since v2:
 - Fix the bindings again, sorry for the spam

Changes since v1:
 - Fix the binding document
 - Change the binding name
 - Clean up the size argument checking
 - Reduce __force by using packed struct for the command

Eddie James (6):
  fsi: Move fsi_slave structure definition to header
  dt-bindings: fsi: Document the IBM I2C Responder virtual FSI master
  fsi: Add IBM I2C Responder virtual FSI master
  fsi: Add I2C Responder SCOM driver
  fsi: Add aliased device numbering
  fsi: Use of_match_table for bus matching if specified
