drivers/fsi: Add empty fsi bus definitions This change adds the initial (empty) fsi bus definition, and introduces drivers/fsi/. Signed-off-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Chris Bostic <cbostic@us.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

drivers/fsi: Implement slave initialisation Implement fsi_slave_init: if we can read a chip ID, create fsi_slave devices and register with the driver core. Includes changes from Christopher Bostic <cbostic@linux.vnet.ibm.com>.

drivers/fsi: Add GPIO based FSI master Implement a FSI master using GPIO. Will generate FSI protocol for read and write commands to particular addresses. Sends master command and waits for and decodes a slave response. Includes changes from Edward A. James <eajames@us.ibm.com> and Jeremy Kerr <jk@ozlabs.org>. Signed-off-by: Edward A.

drivers/fsi: Add hub master support Add an engine driver to expose a "hub" FSI master - which has a set of control registers in the engine address space, and uses a chunk of the slave address space for actual FSI communication. Additional changes from Jeremy Kerr <jk@ozlabs.org>.

drivers/fsi: Add SCOM FSI client device driver Create a simple SCOM engine device driver that reads and writes its control registers via an FSI bus. Includes changes from Edward A.
