Hello everyone,

This is version three of my series that adds support for a Gigabit Ethernet
controller featured in the Renesas r9a06g032 SoC, of the RZ/N1 family. This
GMAC device is based on a Synopsys IP and is compatible with the stmmac driver.

My former colleague Clément Léger originally sent a series for this driver,
but an issue in bringing up the PCS clock had blocked the upstreaming
process. This issue has since been resolved by the following series:

https://lore.kernel.org/all/20240326-rxc_bugfix-v6-0-24a74e5c761f@bootlin.com/

This series consists of a devicetree binding describing the RZN1 GMAC
controller IP, a node for the GMAC1 device in the r9a06g032 SoC device
tree, and the GMAC driver itself which is a glue layer in stmmac.

There are also two patches by Russell that improve pcs initialization handling
in stmmac.

Best Regards,

Romain Gantois
