[PATCH v8 0/8] fsi: Add IBM I2C Responder virtual FSI master

[Eddie James]

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 v7:
 - Add FSI master device naming patch
 - Use I2C adapter number as FSI master index with "i2cr" name
 - Export the fsi_master_i2cr_read/write functions for the SCOM driver

Changes since v6:
 - Drop conversions to BE except in the FSI core interface
 - Emulate the CFAM config table since it doesn't exist off the I2CR
 - Drop status check during probe
 - Add release function for device
 - Update SCOM driver with newer interfaces and drop BE conversion
 - New sbefifo change to not check state during probe

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
