| |
From: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com>
On RZ/G3S different Ethernet pins needs to be configured with different settings (e.g. power-source need to be set, RGMII TXC, TX_CTL pins need output-enable). Commit adjust driver to allow specifying pin configuration for pinmux groups. With this DT settings like the following are taken into account by driver:
eth0_pins: eth0 { tx_ctl { pinmux = <RZG2L_PORT_PINMUX(1, 1, 1)>; /* ET0_TX_CTL */ power-source = <1800>; output-enable; drive-strength-microamp = <5200>; }; };
