From 79d83b3a458eaebb98033424e035cb9091291c68 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Thu, 12 May 2022 11:12:46 +0300 Subject: [PATCH] ARM: dts: lan966x: add basic Kontron KSwitch D10 support Add basic support for the Kontron KSwitch D10 MMT. It comes in two variants: "6G-2GS" which features 6 Gigabit copper ports and two SFP cages and "8G" which features 6 Gigbabit copper ports (where two are 2.5G capable). For now the following is supported and working: - Kernel console - SFP cages - SPI - SGPIO - Watchdog Signed-off-by: Michael Walle Reviewed-by: Claudiu Beznea Tested-by: Horatiu Vultur [claudiu.beznea: fixed conflict on Makefile] Signed-off-by: Claudiu Beznea Link: https://lore.kernel.org/r/20220502224127.2604333-8-michael@walle.cc Signed-off-by: Nicolas Ferre --- arch/arm/boot/dts/Makefile | 4 +- ...lan966x-kontron-kswitch-d10-mmt-6g-2gs.dts | 78 ++++++++++++++++ .../lan966x-kontron-kswitch-d10-mmt-8g.dts | 13 +++ .../dts/lan966x-kontron-kswitch-d10-mmt.dtsi | 93 +++++++++++++++++++ 4 files changed, 187 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/lan966x-kontron-kswitch-d10-mmt-6g-2gs.dts create mode 100644 arch/arm/boot/dts/lan966x-kontron-kswitch-d10-mmt-8g.dts create mode 100644 arch/arm/boot/dts/lan966x-kontron-kswitch-d10-mmt.dtsi diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 7c16f8a2b738..54beef7c1810 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -742,7 +742,9 @@ dtb-$(CONFIG_SOC_IMX7ULP) += \ imx7ulp-com.dtb \ imx7ulp-evk.dtb dtb-$(CONFIG_SOC_LAN966) += \ - lan966x-pcb8291.dtb + lan966x-pcb8291.dtb \ + lan966x-kontron-kswitch-d10-mmt-6g-2gs.dtb \ + lan966x-kontron-kswitch-d10-mmt-8g.dtb dtb-$(CONFIG_SOC_LS1021A) += \ ls1021a-moxa-uc-8410a.dtb \ ls1021a-qds.dtb \ diff --git a/arch/arm/boot/dts/lan966x-kontron-kswitch-d10-mmt-6g-2gs.dts b/arch/arm/boot/dts/lan966x-kontron-kswitch-d10-mmt-6g-2gs.dts new file mode 100644 index 000000000000..7b12cbe11c58 --- /dev/null +++ b/arch/arm/boot/dts/lan966x-kontron-kswitch-d10-mmt-6g-2gs.dts @@ -0,0 +1,78 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * Device Tree file for the Kontron KSwitch D10 MMT 6G-2GS + */ + +/dts-v1/;
