* fsi: Make FSI a menuconfig to ease disabling it allVincent Legoll2017-12-071-5/+1
| | | | | | | | No need to get into the submenu to disable all FSI-related config entries Signed-off-by: Vincent Legoll <vincent.legoll@gmail.com> Acked-by: Jeremy Kerr <jk@ozlabs.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* drivers/fsi: Add hub master supportChristopher Bostic2017-06-091-0/+8
| | | | | | | | | | | | | 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 driverChristopher Bostic2017-06-091-0/+5
| | | | | | | | | | | | | Create a simple SCOM engine device driver that reads and writes its control registers via an FSI bus. Includes changes from Edward A. James <eajames@us.ibm.com>.

* drivers/fsi: Add GPIO based FSI masterChristopher Bostic2017-06-091-0/+12
| | | | | | | | | | | | | | | 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: Implement slave initialisationJeremy Kerr2017-06-091-0/+1
| | | | | | | | | | | | Implement fsi_slave_init: if we can read a chip ID, create fsi_slave devices and register with the driver core.

* drivers/fsi: Add empty fsi bus definitionsJeremy Kerr2017-02-101-0/+12
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>
