Import pending series introducing support for standalone PCS drivers. This has previously already been used by the airoha target, and is also the base for the closer-to-upstream patches for MediaTek MT7988 10G SerDes support. In order to not having to diverge from upstream also backport series for standardized handling for PHY and PCS SerDes pair polarity. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

Subject: [PATCH 6/7] dt-bindings: net: ethernet-controller: permit to define
|
|
multiple PCS
|
|
|
|
Drop the limitation of a single PCS in pcs-handle property. Multiple PCS
|
|
can be defined for an ethrnet-controller node to support various PHY
|
|
interface mode type.
|
|
|
|
It's very common for SoCs to have a dedicated PCS for SGMII mode and one
|
|
for USXGMII mode.
