[PATCH v3 0/2] Add support for CPSW3G port 2 on AM62A7-SK

[PATCH v3 0/2] Add support for CPSW3G port 2 on AM62A7-SK

[Chintan Vankar]

Hello,

This series adds support for CPSW3G MAC port 2 with the SK-Ethernet-DC01
Add-On daughtercard. Also, the missing alias for CPSW3G MAC Port 1 is
added to the am62a7-sk board file in order to allow kernel to fetch MAC
address populated by U-Boot for CPSW3G MAC Port 1.

This series is based on linux-next tagged next-20240429.

Link to v2:
https://lore.kernel.org/r/20240425102038.1995252-1-c-vankar@ti.com/

Changes from v2 to v3:
- Updated SPDX-License-Identifier and "pinctrl-0" property in "cpsw3g"
  node in "k3-am62a7-sk-ethernet-dc01.dtso" as suggested by Ravi.

[PATCH v3 1/2] arm64: dts: ti: k3-am62a7-sk: Add alias for CPSW3G MAC port 1

[Chintan Vankar]

From: Siddharth Vadapalli <s-vadapalli@ti.com>

Add alias for CPSW3G MAC port 1 to enable kernel to fetch MAC Address
directly from U-Boot.

[PATCH v3 2/2] arm64: dts: ti: k3-am62a7: Add overlay for second CPSW3G Port

[Chintan Vankar]

From: Siddharth Vadapalli <s-vadapalli@ti.com>

The SK-Ethernet-DC01 Add-On Ethernet Card for AM62A7-SK board supports
RGMII mode.

Add overlay to enable the second CPSW3G port in RGMII-RXID mode with the
Add-On Ethernet Card.
