Subject: [PATCH v2 0/9] Configure GbEth for RGMII on RZ/G2L family
Date: Tue, 11 Jun 2024 12:31:54 +0100

For devices in the RZ/G2L family, we have so far relied on U-Boot
correctly configuring the Ethernet interfaces in RGMII mode with
PVDD=1.8V before the kernel is booted. Instead, the required
configuration should be described in the device tree and activated
within the pinctrl driver.

Changes v1-v2:
  * Rebased on next-20240611.
  * Changed the approach taken in the pinctrl patches to be compatible
    with changes made by Prabhakar for RZ/V2H support. I haven't picked
    up Reviewed-by tags on these patches as they've changed a lot.
  * Clarified that patch 6/9 also affects RZ/Five.
  * No major changes to the dts patches so I've picked up Geert's
    Reviewed-by tags for these.
