Replace previous patch adding paths and SerDes modes with patch series pending upstream adding dedicated drivers for XFI T-PHY and USXGMII PCS, extends LynxI PCS to be a standalone platform driver and as a consequence makes much less changes to the actual Ethernet driver mtk_eth_soc.

Subject: [PATCH 4/5] dt-bindings: net: pcs: add bindings for MediaTek USXGMII
|
|
PCS
|
|
|
|
MediaTek's USXGMII can be found in the MT7988 SoC. We need to access
|
|
it in order to configure and monitor the Ethernet SerDes link in
|
|
USXGMII, 10GBase-R and 5GBase-R mode. By including a wrapped
|
|
legacy 1000Base-X/2500Base-X/Cisco SGMII LynxI PCS as well, those
|
|
interface modes are also available.

+description:
|
|
+ The MediaTek USXGMII PCS provides physical link control and status
|
|
+ for USXGMII, 10GBase-R and 5GBase-R links on the SerDes interfaces
|
|
+ provided by the PEXTP PHY.
|
|
+ In order to also support legacy 2500Base-X, 1000Base-X and Cisco
|
|
+ SGMII an existing mediatek,*-sgmiisys LynxI PCS is wrapped to
|
|
+ provide those interfaces modes on the same SerDes interfaces shared
|
|
+ with the USXGMII PCS.
