Allow a master to undo a previous scan. Should a master scan a bus twice it will need to ensure it doesn't double register any previously detected device. Signed-off-by: Christopher Bostic Signed-off-by: Joel Stanley v7 - Unscan when

[PATCH v8 00/24] FSI device driver implementation

Implementation of the IBM 'Flexible Support Interface' (FSI) bus device driver. FSI is a high fan out serial bus consisting of a clock and a serial data line capable of running at speeds up to 166 MHz. This set provides the basic framework to add FSI extensions to the Linux bus and device models.

[PATCH v8 05/24] drivers/fsi: Add slave & master read/write APIs

From: Jeremy Kerr Introduce functions to perform reads/writes on the slave address space; these simply pass the request on the slave's master with the correct link and slave ID. We implement these on top of similar helpers for the master. Signed-off-by: Jeremy Kerr

[PATCH v8 01/24] drivers/fsi: Add fsi master definition

From: Jeremy Kerr Add a `struct fsi_master` to represent a FSI master controller. FSI master drivers register one of these structs to provide device-specific of the standard operations: read/write/term/break and link control. Includes changes from Edward A. James

Define the target port membership of the VLAN entry in mv88e6xxx_port_vlan_add where ds is scoped. Allow the DSA core to call later the port_vlan_add operation for CPU or DSA ports, by using the Unmodified membership for these ports, as in the current behavior. Signed-off-by: Vivien Didelot

In a multi-chip switch fabric, it is currently the responsibility of the driver to add the CPU or DSA (interconnecting chips together) ports as members of a new VLAN entry. This makes the drivers more complicated. We want the DSA drivers to be stupid and the DSA core being the one responsible for

[PATCH net-next 5/5] net: dsa: mv88e6xxx: do not purge a VTU entry

The mv88e6xxx driver currently tries to be smart and remove by itself a VLAN entry from the VTU when the driven switch sees no user ports as members of the VLAN. This is bad in a multi-chip switch fabric, since a chip in between others may have no bridge port members, but still needs to be aware
