We need to split out the non common IPs (e.g. USB) out of the common k3-am62p-main.dtsi file Maybe call it k3-am62-main-common.dtsi. Only keep am62p specific stuff in k3-am62p-main.dtsi. Include k3-am62-main-common.dtsi and k3-am62p-main.dtsi for AM62P Include k3-am62-main-common.dtsi and k3-j722s-main.dtsi for J722S This way you don't need to call /delete-node/ > / { > serdes_refclk: clk-0 { > compatible = "fixed-clock"; > @@ -52,6 +59,38 @@ serdes0: serdes@f000000 { > status = "disabled"; /* Needs lane config */ > }; > }; > + > + usbss1: usb@f920000 { > + compatible = "ti,j721e-usb"; > + reg = <0x00 0x0f920000 0x00 0x100>; > + power-domains = <&k3_pds 278 TI_SCI_PD_EXCLUSIVE>; > + clocks = <&k3_clks 278 3>, <&k3_clks 278 1>; > + clock-names = "ref", "lpm"; > + assigned-clocks = <&k3_clks 278 3>; /* USB2_REFCLK */ > + assigned-clock-parents = <&k3_clks 278 4>; /* HF0SC0 */ > + #address-cells = <2>; > + #size-cells = <2>; > + ranges; > + status = "disabled"; > + > + usb1: usb@31200000{ > + compatible = "cdns,usb3"; > + reg = <0x00 0x31200000 0x00 0x10000>, > + <0x00 0x31210000 0x00 0x10000>, > + <0x00 0x31220000 0x00 0x10000>; > + reg-names = "otg", > + "xhci", > + "dev"; > + interrupts = <GIC_SPI 226 IRQ_TYPE_LEVEL_HIGH>, /* irq.0 */ > + <GIC_SPI 232 IRQ_TYPE_LEVEL_HIGH>, /* irq.6 */ > + <GIC_SPI 245 IRQ_TYPE_LEVEL_HIGH>; /* otgirq */ > + interrupt-names = "host", > + "peripheral", > + "otg"; > + maximum-speed = "super-speed"; > + dr_mode = "otg"; > + }; > + }; > }; > > &main_conf { -- cheers, -roger
