Hello everyone, This is version one 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@xxxxxxxxxxx/ 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.
