net: remove phylink_pcs .neg_mode boolean

2025-02-15T01:09:50+00:00

As all PCS are using the neg_mode parameter rather than the legacy an_mode, remove the ability to use the legacy an_mode. We remove the tests in the phylink code, unconditionally passing the PCS neg_mode parameter to PCS methods, and remove setting the flag from drivers.

Documentation/process/license-rules.rst and checkpatch expect the SPDX identifier syntax for multiple licenses to use capital "OR". Correct it to keep consistent format and avoid copy-paste issues.

Update B53's embedded PCS driver to use neg_mode, even though it makes no use of it or the "mode" argument. This makes the driver consistent with converted drivers.

net: dsa: b53: Add SerDes support

2018-09-06T14:48:34+00:00

Add support for the Northstar Plus SerDes which is accessed through a special page of the switch. Since this is something that most people probably will not want to use, make it a configurable option with a default on ARCH_BCM_NSP where it is the most useful currently. The SerDes supports both SGMII and 1000baseX modes for both lanes, and 2500baseX for one of the lanes, and is internally looking like a seemingly standard MII PHY, except for the few bits that got repurposed.
