net: dsa: Add support for devlink resources

2019-11-06T02:09:45+00:00

Add wrappers around the devlink resource API, so that DSA drivers can
register and unregister devlink resources.

net: dsa: Add support for devlink device parameters

2019-10-28T23:21:02+00:00

Add plumbing to allow DSA drivers to register parameters with devlink.

To keep with the abstraction, the DSA drivers pass the ds structure to
these helpers, and the DSA core then translates that to the devlink
structure associated to the device.

net: dsa: use dsa_to_port helper everywhere

2019-10-22T19:37:06+00:00

Do not let the drivers access the ds->ports static array directly
while there is a dsa_to_port helper for this purpose.

At the same time, un-const this helper since the SJA1105 driver
assigns the priv member of the returned dsa_port structure.

dsa: Make use of the list of tag drivers

2019-04-28T23:41:01+00:00

Implement the _get and _put functions to make use of the list of tag
drivers. Also, trigger the loading of the module, based on the alias
information. The _get function takes a reference on the tag driver, so
it cannot be unloaded, and the _put function releases the reference.

dsa: Add stub tag driver put method

2019-04-28T23:41:01+00:00

When a DSA switch driver is unloaded, the lock on the tag driver
should be released so the module can be unloaded. Add the needed calls,
but leave the actual release code as a stub.
