net: dsa: mt7530: fix module autoloading for OF platform drivers

2018-03-26T17:09:42+00:00

It's required to create a modules.alias via MODULE_DEVICE_TABLE helper for the OF platform driver. Otherwise, module autoloading cannot work. Signed-off-by: Sean Wang Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: mt7530: remove redundant MODULE_ALIAS entries

2018-03-26T17:09:41+00:00

MODULE_ALIAS exports information to allow the module to be auto-loaded at boot for the drivers registered using legacy platform registration. However, currently the driver is always used by DT-only platform, MODULE_ALIAS is redundant and should be removed properly. Signed-off-by: Sean Wang Reviewed-by: Andrew Lunn Signed-off-by: David S.

net: dsa: mediatek: add VLAN support for MT7530

2017-12-15T15:31:54+00:00

MT7530 can treat each port as either VLAN-unaware port or VLAN-aware port through the implementation of port matrix mode or port security mode on the ingress port, respectively. On one hand, Each port has been acting as the VLAN-unaware one whenever the device is created in the initial or certain port joins or leaves into/from the bridge at the runtime. On the other hand, the patch just filling the required callbacks for VLAN operations is achieved via extending the port to be into port security mode when the port is configured as VLAN-aware port. Which mode can make the port be able to recognize VID from incoming packets and look up VLAN table to validate and judge which port it should be going to. And the range for VID from 1 to 4094 is valid for the hardware. Signed-off-by: Sean Wang Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: Pass a port to get_tag_protocol()

2017-11-13T01:34:54+00:00

A number of drivers want to check whether the configured CPU port is a possible configuration for enabling tagging, pass down the CPU port number so they verify that. Signed-off-by: Florian Fainelli Reviewed-by: Vivien Didelot Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: introduce dsa_user_ports helper

2017-10-27T15:00:09+00:00

Introduce a dsa_user_ports() helper to return the ds->enabled_port_mask mask which is more explicit. This will also minimize diffs when touching this internal mask. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: use dsa_is_user_port everywhere

2017-10-27T15:00:09+00:00

Most of the DSA code still check ds->enabled_port_mask directly to inspect a given port type instead of using the provided dsa_is_user_port helper. Change this. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: add dsa_to_port helper

2017-10-18T11:24:33+00:00

The dsa_port structure is part of DSA core data and must only be updated by the later. It is OK and sometimes necessary for the DSA drivers to access this data, but this has to be read only. For that purpose, add a dsa_to_port() helper which returns a const pointer to a dsa_port structure which must be used by DSA drivers from now on instead of digging into ds->ports[] themselves.

net: dsa: split dsa_port's netdev member

2017-10-18T11:24:33+00:00

The dsa_port structure has a "netdev" member, which can be used for either the master device, or the slave device, depending on its type. It is true that today, CPU port are not exposed to userspace, thus the port's netdev member can be used to point to its master interface. But it is still slightly confusing, so split it into more explicit "master" and "slave" members inside an anonymous union. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: mt7530: make functions mt7530_phy_write static

2017-10-03T17:20:12+00:00

The function mt7530_phy_write is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warnings: symbol 'mt7530_phy_write' was not declared. Should it be static? Signed-off-by: Colin Ian King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: dsa: use dedicated CPU port

2017-09-21T22:15:58+00:00

Each port in DSA has its own dedicated CPU port currently available in its parent switch's ds->ports[port].cpu_dp. Use it instead of getting the unique tree CPU port, which will be deprecated soon. Signed-off-by: Vivien Didelot Reviewed-by: Florian Fainelli Signed-off-by: David S. Miller
