Each IEP sub-module is sourced from an internal clock mux that can be derived from either of the IP instance's ICSSG_IEP_GCLK or from another internal ICSSG CORE_CLK mux. Add both the IEP nodes for both the ICSSG instances. The IEP clock is currently configured to be derived indirectly from the ICSSG_ICLK running at 250 MHz.

The ICSSG1 MII0 (RGMII1) has DP83869 PHY attached to it. The ICSSG1 shares MII1 (RGMII2) PHY DP83869 with CPSW3g and it's assigned by default to CPSW3g. The MDIO access to MII1 (RGMII2) PHY DP83869 is controlled by MDIO bus switch and also assigned to CPSW3g. Therefore the ICSSG1 MII1 (RGMII2) port is kept disable and ICSSG1 is enabled in single MAC mode by default.

This patch adds overlay to support 1 x CPSW3g ports and 2 x ICSSG1 ports configuration: - Add label name 'mdio_mux_1' for 'mdio-mux-1' node so that the node 'mdio-mux-1' can be disabled in the overlay using the label name. - disable 2nd CPSW3g port - update CPSW3g pinmuxes to not use RGMII2 - disable mdio-mux-1 and define mdio-mux-2 to route ICSSG1 MDIO to the shared DP83869 PHY - add and enable ICSSG1 RGMII2 pinmuxes - enable ICSSG1 MII1 port Reviewed-by: Ravi Gunasekaran Reviewed-by: Roger Quadros Signed-off-by: MD Danish Anwar --- arch/arm64/boot/dts/ti/Makefile | 5 ++ .../dts/ti/k3-am642-evm-icssg1-dualemac.dtso | 79 +++++++++++++++++++ arch/arm64/boot/dts/ti/k3-am642-evm.dts | 2 +- 3 files changed, 85 insertions(+), 1 deletion(-) create mode 100644 arch/arm64/boot/dts/ti/k3-am642-evm-icssg1-dualemac.dtso diff --git a/arch/arm64/boot/dts/ti/Makefile b/arch/arm64/boot/dts/ti/Makefile index 4a570dffb638..2d255f31b3a6 100644 --- a/arch/arm64/boot/dts/ti/Makefile +++ b/arch/arm64/boot/dts/ti/Makefile @@ -43,6 +43,7 @@ dtb-$(CONFIG_ARCH_K3) += k3-am642-sk.dtb dtb-$(CONFIG_ARCH_K3) += k3-am642-tqma64xxl-mbax4xxl.dtb dtb-$(CONFIG_ARCH_K3) += k3-am64-tqma64xxl-mbax4xxl-sdcard.dtbo dtb-$(CONFIG_ARCH_K3) += k3-am64-tqma64xxl-mbax4xxl-wlan.dtbo +dtb-$(CONFIG_ARCH_K3) += k3-am642-evm-icssg1-dualemac.dtbo # Boards with AM65x SoC k3-am654-gp-evm-dtbs := k3-am654-base-board.dtb k3-am654-base-board-rocktech-rk101-panel.dtbo @@ -106,6 +107,8 @@ k3-am642-tqma64xxl-mbax4xxl-sdcard-dtbs := \ k3-am642-tqma64xxl-mbax4xxl.dtb k3-am64-tqma64xxl-mbax4xxl-sdcard.dtbo k3-am642-tqma64xxl-mbax4xxl-wlan-dtbs := \ k3-am642-tqma64xxl-mbax4xxl.dtb k3-am64-tqma64xxl-mbax4xxl-wlan.dtbo +k3-am642-evm-icssg1-dualemac-dtbs := \ + k3-am642-evm.dtb k3-am642-evm-icssg1-dualemac.dtbo k3-j721e-evm-pcie0-ep-dtbs := k3-j721e-common-proc-board.dtb \ k3-j721e-evm-pcie0-ep.dtbo k3-j721s2-evm-pcie1-ep-dtbs := k3-j721s2-common-proc-board.dtb \ @@ -122,6 +125,7 @@ dtb- += k3-am625-beagleplay-csi2-ov5640.dtb \ k3-am62a7-sk-hdmi-audio.dtb \ k3-am642-tqma64xxl-mbax4xxl-sdcard.dtb \ k3-am642-tqma64xxl-mbax4xxl-wlan.dtb \ + k3-am642-evm-icssg1-dualemac.dtb \ k3-j721e-evm-pcie0-ep.dtb \ k3-j721s2-evm-pcie1-ep.dtb @@ -131,6 +135,7 @@ DTC_FLAGS_k3-am625-sk += -@ DTC_FLAGS_k3-am62-lp-sk += -@ DTC_FLAGS_k3-am62a7-sk += -@ DTC_FLAGS_k3-am642-tqma64xxl-mbax4xxl += -@ +DTC_FLAGS_k3-am642-evm += -@ DTC_FLAGS_k3-am6548-iot2050-advanced-m2 += -@ DTC_FLAGS_k3-j721e-common-proc-board += -@ DTC_FLAGS_k3-j721s2-common-proc-board += -@ diff --git a/arch/arm64/boot/dts/ti/k3-am642-evm-icssg1-dualemac.dtso b/arch/arm64/boot/dts/ti/k3-am642-evm-icssg1-dualemac.dtso new file mode 100644 index 000000000000..af2fd3e7448b --- /dev/null +++ b/arch/arm64/boot/dts/ti/k3-am642-evm-icssg1-dualemac.dtso @@ -0,0 +1,79 @@ +// SPDX-License-Identifier: GPL-2.0-only OR MIT +/** + * DT overlay for enabling 2nd ICSSG1 port on AM642 EVM + * + * Copyright (C) 2020-2024 Texas Instruments Incorporated - https://www.ti.com/ + */ + +/dts-v1/;
