| 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.
