From 06c895f5d3a98669aa0f6ac3a06815474e57234d Mon Sep 17 00:00:00 2001 From: Markus Stockhausen Date: Thu, 18 Sep 2025 05:10:50 -0400 Subject: [PATCH] realtek: DTS: add macro for switch port with SerDes In the future the PCS & DSA drivers will lookup the SerDes of a switch port via pcs-handle (like upstream does). Provide a macro that allows to expand the existing port definitions. To link a SerDes to port simply do Either in short form: replace SWITCH_PORT(0, 1, qsgmii) with SWITCH_PORT_SDS(0, 1, 3, qsgmii) (Link to SerDes 3) Or in long form: port@24 { reg = <24>; label = "lan25"; pcs-handle = <&serdes4>; (Link to SerDes 4) phy-handle = <&phy24>; phy-mode = "1000base-x"; managed = "in-band-status"; sfp = <&sfp0>; }; Signed-off-by: Markus Stockhausen Link: https://github.com/openwrt/openwrt/pull/20075 Signed-off-by: Robert Marko --- target/linux/realtek/dts/macros.dtsi | 19 ++++++++++++++----- 1 file changed, 14 insertions(+), 5 deletions(-) diff --git a/target/linux/realtek/dts/macros.dtsi b/target/linux/realtek/dts/macros.dtsi index b47b782669..fbdd3fbb1c 100644 --- a/target/linux/realtek/dts/macros.dtsi +++ b/target/linux/realtek/dts/macros.dtsi @@ -42,11 +42,20 @@ reg = <##n>; \ }; -#define SWITCH_PORT(n, s, m) \ - port##n: port@##n { \ - reg = <##n>; \ - label = SWITCH_PORT_LABEL(s) ; \ - phy-handle = <&phy##n>; \ +#define SWITCH_PORT(p, l, m) \ + port##p: port@##p { \ + reg = <##p>; \ + label = SWITCH_PORT_LABEL(l) ; \ + phy-handle = <&phy##p>; \ + phy-mode = #m ; \ + }; + +#define SWITCH_PORT_SDS(p, l, s, m) \ + port##p: port@##p { \ + reg = <##p>; \ + label = SWITCH_PORT_LABEL(l) ; \ + pcs-handle = <&serdes##s>; \ + phy-handle = <&phy##p>; \ phy-mode = #m ; \ }; -- 2.30.2
