dsa: Rename switch chip data to cd

2016-05-11T23:36:28Z

The dsa_switch structure contains a dsa_chip_data member called pd. However in the rest of the code, pd is used for dsa_platform_data. This is confusing. Rename it cd, which is already often used in dsa.c and slave.c for this data type. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

dsa: Remove master_dev from switch structure

2016-05-11T23:36:28Z

The switch drivers only use the master_dev member for dev_info() messages. Now that the device is passed to the old style probe, and new style drivers are probed as true linux drivers, this is no longer needed. Signed-off-by: Andrew Lunn Signed-off-by: David S. Miller

dsa: Move gpio reset into switch driver

2016-05-11T23:36:28Z

Resetting the switch is something the driver does, not the framework. So move the parsing of this property into the driver. There are no in kernel users of this property, so moving it does not break anything. There is however a board which will make use of this property making its way into the kernel.

net: dsa: Provide CPU port statistics to master netdev

2016-04-28T21:16:17Z

This patch overloads the DSA master netdev, aka CPU Ethernet MAC to also include switch-side statistics, which is useful for debugging purposes, when the switch is not properly connected to the Ethernet MAC (duplex mismatch, (RG)MII electrical issues etc.). We accomplish this by retaining the original copy of the master netdev's ethtool_ops, and just overload the 3 operations we care about: get_sset_count, get_strings and get_ethtool_stats so as to intercept these calls and call into the original master_netdev ethtool_ops, plus our own. We take this approach as opposed to providing a set of DSA helper functions that would retrive the CPU port's statistics, because the entire purpose of DSA is to allow unmodified Ethernet MAC drivers to be used as CPU conduit interfaces, therefore, statistics overlay in such drivers would simply not scale. The new ethtool -S output would therefore look like this now: statistics p<2 digits cpu port number>_ Signed-off-by: Florian Fainelli Signed-off-by: David S. Miller

net: dsa: remove tag_protocol from dsa_switch

2016-04-21T17:43:11Z

Having the tag protocol in dsa_switch_driver for setup time and in dsa_switch_tree for runtime is enough. Remove dsa_switch's one. Signed-off-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: constify probed name

Change the dsa_switch_driver.probe function to return a const char *. Signed-off-by: Vivien Didelot Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

dsa: Rename phys_port_mask to enabled_port_mask

2016-04-13T22:15:23Z

The phys in phys_port_mask suggests this mask is about PHYs. In fact, it means physical ports. Rename to enabled_port_mask, indicating external enabled ports of the switch, which is hopefully less confusing.

net: dsa: Remove allocation of driver private memory

2016-04-13T22:15:23Z

The drivers now allocate their own memory for private usage. Remove the allocation from the core code. Signed-off-by: Andrew Lunn Acked-by: Florian Fainelli Tested-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: Have the switch driver allocate there own private memory

2016-04-13T22:15:23Z

Now the switch devices have a dev pointer, make use of it for allocating the drivers private data structures using a devm_kzalloc(). Signed-off-by: Andrew Lunn Acked-by: Florian Fainelli Tested-by: Vivien Didelot Signed-off-by: David S. Miller

net: dsa: Pass the dsa device to the switch drivers

2016-04-13T22:15:22Z

By passing a device structure to the switch devices, it allows them to use devm_* methods for resource management. Signed-off-by: Andrew Lunn Acked-by: Florian Fainelli Tested-by: Vivien Didelot Signed-off-by: David S. Miller
