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 1/5] dt-bindings: phy: rename transmit-amplitude.yaml to
|
|
phy-common-props.yaml
|
|
|
|
I would like to add more properties similar to tx-p2p-microvolt, and I
|
|
don't think it makes sense to create one schema for each such property
|
|
(transmit-amplitude.yaml, lane-polarity.yaml, transmit-equalization.yaml
|
|
etc).
|
|
|
|
Instead, let's rename to phy-common-props.yaml, which makes it a more
|
|
adequate host schema for all the above properties.
