-	  This is a driver for the General Instrument (also known as
-	  NextLevel) SURFboard 1000 internal
-	  cable modem. This is an ISA card which is used by a number of cable
-	  TV companies to provide cable modem access. It's a one-way
-	  downstream-only cable modem, meaning that your upstream net link is
-	  provided by your regular phone modem.
-
-	  At present this driver only compiles as a module, so say M here if
-	  you have this card. The module will be called sb1000. Then read
-	  <file:Documentation/networking/device_drivers/cable/sb1000.rst> for
-	  information on how to use this module, as it needs special ppp
-	  scripts for establishing a connection. Further documentation
-	  and the necessary scripts can be found at:
-
-	  <http://www.jacksonville.net/~fventuri/>
-	  <http://home.adelphia.net/~siglercm/sb1000.html>

+ *
+ * The hardware has 64 possible table entries for bridges with one VLAN
+ * ID, one flow id and a list of ports for each bridge. All entries which
+ * match the same flow ID are combined in the mac learning table, they
+ * act as one global bridge.
+ * The hardware does not support VLAN filter on the port, but on the
+ * bridge, this driver converts the DSA model to the hardware.
+ *
+ * The CPU gets all the exception frames which do not match any forwarding
+ * rule and the CPU port is also added to all bridges. This makes it possible
+ * to handle all the special cases easily in software.
+ * At the initialization the driver allocates one bridge table entry for
+ * each switch port which is used when the port is used without an
+ * explicit bridge. This prevents the frames from being forwarded
+ * between all LAN ports by default.

- * The VLAN and bridge model the GSWIP hardware uses does not directly
- * matches the model DSA uses.
- *
- * The hardware has 64 possible table entries for bridges with one VLAN
- * ID, one flow id and a list of ports for each bridge. All entries which
- * match the same flow ID are combined in the mac learning table, they
- * act as one global bridge.
- * The hardware does not support VLAN filter on the port, but on the
- * bridge, this driver converts the DSA model to the hardware.
- *
- * The CPU gets all the exception frames which do not match any forwarding
- * rule and the CPU port is also added to all bridges. This makes it possible
- * to handle all the special cases easily in software.
- * At the initialization the driver allocates one bridge table entry for
- * each switch port which is used when the port is used without an
- * explicit bridge. This prevents the frames from being forwarded
- * between all LAN ports by default.

+ *
+ * Hardware Management of EEE/LPI State:
+ * For KSZ switch ports with integrated PHYs (e.g., KSZ9893R ports 1-2),
+ * observation and testing suggest that the actual EEE / Low Power Idle (LPI)
+ * state transitions are managed autonomously by the hardware based on
+ * the auto-negotiation results. (Note: While the datasheet describes EEE
+ * operation based on negotiation, it doesn't explicitly detail the internal
+ * MAC/PHY interaction, so autonomous hardware management of the MAC state
+ * for LPI is inferred from observed behavior).
+ * This hardware control, consistent with the switch's ability to operate
+ * autonomously via strapping, means MAC-level software intervention is not
+ * required or exposed for managing the LPI state once EEE is negotiated.
+ * (Ref: KSZ9893R Data Sheet DS00002420D, primarily Section 4.7.5 explaining
+ * EEE, also Sections 4.1.7 on Auto-Negotiation and 3.2.1 on Configuration
+ * Straps).
+ *
+ * Additionally, ports configured as MAC interfaces (e.g., KSZ9893R port 3)
+ * lack documented MAC-level LPI control.
+ *
+ * Therefore, this callback performs no action and serves primarily to inform
+ * phylink of LPI awareness and to document the inferred hardware behavior.

+ *
+ * This function sets up the PHY address mapping for the LAN937x switches,
+ * which support two access modes for internal PHYs:
+ * 1. **SPI Access**: A straightforward one-to-one port-to-PHY address
+ *    mapping is applied.
+ * 2. **MDIO Access**: The PHY address mapping varies based on chip variant
+ *    and strap configuration. An offset is calculated based on strap settings
+ *    to ensure correct PHY addresses are assigned. The offset calculation logic
+ *    is based on Microchip's Article Number 000015828, available at:
+ *    https://microchip.my.site.com/s/article/LAN9374-Virtual-PHY-PHY-Address-Mapping
+ *
+ * The function first checks if side MDIO access is disabled, in which case a
+ * simple direct mapping (port number = PHY address) is applied. If side MDIO
+ * access is enabled, it reads the strap configuration to determine the correct
+ * offset for PHY addresses.
+ *
+ * The appropriate mapping table is selected based on the chip ID, and the
+ * `phy_addr_map` is populated with the correct addresses for each port. Any
+ * port with no PHY is assigned a `LAN937X_NO_PHY` marker.
+ *
+ * Return: 0 on success, error code on failure.

+ * 2. **MDIO Access**: Grants access to internal PHYs over the side MDIO bus,
