[PATCH v2 0/5] fsi: Add regmap and refactor sbefifo

The SBEFIFO hardware can now be attached over a new I2C endpoint interface
called the I2C Responder (I2CR). In order to use the existing SBEFIFO
driver, add a regmap driver for the FSI bus and an endpoint driver for the
I2CR. Then, refactor the SBEFIFO and OCC drivers to clean up and use the
new regmap driver or the I2CR interface.

Changes since v1:
 - Instead of a regmap driver for the I2CR, just have a private interface
   driver for FSI, since SBEFIFO is likely the only user.

Eddie James (5):
  regmap: Add FSI bus support
  drivers: fsi: Add I2C Responder driver
  drivers: fsi: Rename sbefifo and occ sources
  drivers: fsi: separate char device code for occ and sbefifo
  drivers: fsi: occ and sbefifo refactor
