Subject: [PATCH v3 0/3] Add support for GBETH IPs found on RZ/G3E SoCs

Hi all,

This series adds support for the two Gigabit Ethernet (GBETH) interfaces on the
Renesas RZ/G3E (R9A09G047) SoCs and their enablement on the SMARC-II EVK. This
is achieved by integrating the necessary clock/reset signals prior to defining
common DTS nodes, and enabling both GBETH ports at the board level.

Here are pach dependencies:

 - Patch 1/3 is based on renesas-drivers tree, on top of renesas-clk-for-v6.17
 branch
 - Patches [2,3]/3  are based on renesas-devel tree, on top of
 renesas-dts-for-v6.17 branch

V1 of this series is located here [1]. It originaly included a patch for
binding documentation, which, in response to Jakub [2], has been resubmited
as a standalone patch for net-next.

V2 can be found here [3].

Changes in v2:
 - Appart from resending the patches and some collected tags, there is no
 changes in V2.
 - Separated binding patch send as standalone patch can be found here [4]

Changes in v3:
 - Fixed consistency with clock names, replacing dashes with underscores
 - Labeled mdio nodes and used phandle-based override instead of node
 redefinition
 - Minor typo fixes

Note for DT maintainers:
Documentation/dt-bindings patch was sent separately and has already been applied here [5]
