Cover letter [PATCH v8 0/8] 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 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
