[PATCH net-next v3 0/2] Update CPSW bindings for Serdes PHY

[Siddharth Vadapalli]

Hello,

This series adds documentation for the Serdes PHY. Also, the name used to
refer to the Serdes PHY in the am65-cpsw driver is updated to match the
documented name.

---
Documenting the Serdes PHY bindings was missed out in the already merged
series at:
https://lore.kernel.org/r/20230104103432.1126403-1-s-vadapalli@ti.com/
This miss was pointed out at:
https://lore.kernel.org/r/CAMuHMdW5atq-FuLEL3htuE3t2uO86anLL3zeY7n1RqqMP_rH1g@mail.gmail.com/

Changes from v2:
1. Drop "phy" suffixes in the phy-names property, changing "mac-phy" and
   "serdes-phy" to "mac" and "serdes".
2. Add a new patch to update the name used by the am65-cpsw driver to
   refer to the Serdes PHY, from "serdes-phy" to "serdes".

Changes from v1:
1. Describe phys property with minItems, items and description.
2. Use minItems and items in phy-names.
3. Remove the description in phy-names.

v2:
https://lore.kernel.org/r/20230308051835.276552-1-s-vadapalli@ti.com/
v1:

[PATCH net-next v3 1/2] dt-bindings: net: ti: k3-am654-cpsw-nuss: Document Serdes PHY

[Siddharth Vadapalli]

Update bindings to include Serdes PHY as an optional PHY, in addition to
the existing CPSW MAC's PHY. The CPSW MAC's PHY is required while the
Serdes PHY is optional. The Serdes PHY handle has to be provided only
when the Serdes is being configured in a Single-Link protocol. Using the
name "serdes-phy" to represent the Serdes PHY handle, the am65-cpsw-nuss
driver can obtain the Serdes PHY and request the Serdes to be
configured.

[PATCH net-next v3 2/2] net: ethernet: ti: am65-cpsw: Update name of Serdes PHY

[Siddharth Vadapalli]

The bindings for the am65-cpsw driver use the name "serdes" to refer to
the Serdes PHY. Thus, update the name used for the Serdes PHY within the
am65_cpsw_init_serdes_phy() function from "serdes-phy" to "serdes".
