How config the spi modules under the spidev3.0 bus in the dts file?

Hi !
Our team designed a new custom board and use a SC16IS752IPW module to expand two uart port? How config the dts file under the spi@3240000 modules?
Ths information of SC16IS752IPW. https://www.nxp.com/docs/en/data-sheet/SC16IS752_SC16IS762.pdf

spi@3240000 {
		compatible = "nvidia,tegra186-spi";
		reg = <0x0 0x3240000 0x0 0x10000>;
		interrupts = <0x0 0x27 0x4>;
		nvidia,dma-request-selector = <0x19 0x12>;
		#address-cells = <0x1>;
		#size-cells = <0x0>;
		#stream-id-cells = <0x1>;
		dmas = <0x19 0x12 0x19 0x12>;
		dma-names = "rx", "tx";
		nvidia,clk-parents = "pll_p", "clk_m";
		clocks = <0xd 0x4a 0xd 0x10d 0xd 0x261>;
		clock-names = "spi", "pll_p", "clk_m";
		resets = <0xd 0x2b>;
		reset-names = "spi";
		status = "okay";
		linux,phandle = <0x7d>;
		phandle = <0x7d>;

		spi@0 {
			compatible = "spidev";
			reg = <0x0>;
			spi-max-frequency = <0x1f78a40>;

			controller-data {
				nvidia,enable-hw-based-cs;
				nvidia,rx-clk-tap-delay = <0x8>;
				nvidia,tx-clk-tap-delay = <0x16>;
			};
		};

		spi@1 {
			compatible = "spidev";
			reg = <0x1>;
			spi-max-frequency = <0x1f78a40>;

			controller-data {
				nvidia,enable-hw-based-cs;
				nvidia,rx-clk-tap-delay = <0x8>;
				nvidia,tx-clk-tap-delay = <0x16>;
			};
		};

		
	};

Hi @365953468

This is the community feedback forum, this should be posted on one of the Embedded Systems forums. Let me reach out to the engineers to find the best home for this topic.

Have a reference to below link for the pinmux configure.
