[PATCH 0/4] Add support for GBETH IPs found on RZ/G3E SoCs

[PATCH 0/4] Add support for GBETH IPs found on RZ/G3E SoCs

[John Madieu]

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 1/4 is based on renesas-drivers tree, on top of renesas-clk-for-v6.17
 branch
 - Patches [2,3,4]/4 are based on renesas-devel tree, on top of
 renesas-dts-for-v6.17 branch

Below are some test logs, involving pings, then unbind/bind, then pings again:

[PATCH 1/4] clk: renesas: r9a09g047: Add clock and reset signals for the GBETH IPs

[John Madieu]

Add clock and reset entries for the Gigabit Ethernet Interfaces (GBETH 0-1)
IPs found on the RZ/G3E SoC. This includes various PLLs, dividers, and mux
clocks needed by these two GBETH IPs.

[PATCH 2/4] dt-bindings: net: renesas-gbeth: Add support for RZ/G3E (R9A09G047) SoC

[John Madieu]

Document support for the GBETH IP found on the Renesas RZ/G3E (R9A09G047) SoC.
The GBETH block on RZ/G3E is equivalent in functionality to the GBETH found on
RZ/V2H(P) (R9A09G057).

Got it. I'll send a v2 with a standalone patch for the binding.
