2017-02-07	net: dsa: Add support for platform data	Florian Fainelli	1	-18/+84
	Allow drivers to use the new DSA API with platform data. Most of the code in net/dsa/dsa2.c does not rely so much on device_nodes and can get the same information from platform_data instead. We purposely do not support distributed configurations with platform data, so drivers should be providing a pointer to a 'struct dsa_chip_data' structure if they wish to communicate per-port layout. Multiple CPUs port could potentially be supported and dsa_chip_data is extended to receive up to one reference to an upstream network device per port described by a dsa_chip_data structure. dsa_dev_to_net_device() increments the network device's reference count, so we intentionally call dev_put() to be consistent with the DT-enabled path, until we have a generic notifier based solution.

2017-02-06	net: dsa: add switch notifier	Vivien Didelot	1	-0/+6
	Add a notifier block per DSA switch, registered against a notifier head in the switch fabric they belong to. This infrastructure will allow to propagate fabric-wide events such as port bridging, VLAN configuration, etc. If a DSA switch driver cares about cross-chip configuration, such events can be caught.
