Why can not enable the SPI1 port at TX1 R28.2?

Please see my dtsi file.

{
	gpio@6000d000 {
	    gpio_default: default {
		   gpio-hog;
           function;
           gpios = <TEGRA_GPIO(C, 0) 0 TEGRA_GPIO(C, 1) 0 TEGRA_GPIO(C, 2) 0 TEGRA_GPIO(C, 3) 0 TEGRA_GPIO(C,4) 0>;
	    };
    };
    
    
    spi@7000d400 {
    	status = "okay";
    	spidev0_0 {
			#address-cells = <0x1>;
			#size-cells = <0x0>;
			compatible = "linux,spidev", "spidev";
			status = "okay";
			reg = <0x0>;
			spi-max-frequency = <40000000>;
			nvidia,enable-hw-based-cs;
			nvidia,cs-setup-clk-count = <0x1e>;
			nvidia,cs-hold-clk-count = <0x1e>;
			nvidia,rx-clk-tap-delay = <0x1f>;
			nvidia,tx-clk-tap-delay = <0x0>;
	    };
    };
    
    spi@7000d600 {
    	status = "okay";
    	spidev1_0 {
			#address-cells = <0x1>;
			#size-cells = <0x0>;
			compatible = "linux,spidev", "spidev";
			status = "okay";
			reg = <0x0>;
			spi-max-frequency = <40000000>;
			nvidia,enable-hw-based-cs;
			nvidia,cs-setup-clk-count = <0x1e>;
			nvidia,cs-hold-clk-count = <0x1e>;
			nvidia,rx-clk-tap-delay = <0x1f>;
			nvidia,tx-clk-tap-delay = <0x0>;
	    };
    };

	
	spi@7000d800 {
    	status = "okay";
    	spidev2_0 {
			#address-cells = <0x1>;
			#size-cells = <0x0>;
			compatible = "linux,spidev", "spidev";
			status = "okay";
			reg = <0x0>;
			spi-max-frequency = <40000000>;
			nvidia,enable-hw-based-cs;
			nvidia,cs-setup-clk-count = <0x1e>;
			nvidia,cs-hold-clk-count = <0x1e>;
			nvidia,rx-clk-tap-delay = <0x1f>;
			nvidia,tx-clk-tap-delay = <0x0>;
	    };
    };

but I can not find the “/dev/spidev1.0” device.as below

nvidia@tegra-ubuntu:~$ ls /dev/spi*
/dev/spidev0.0  /dev/spidev2.0

How can I fix this question?

I cannot answer the specific issue, but do extract the device tree from the running system to see if the change actually made its way in. Procedures for changing device tree change depending on release.

dtc -I fs -O dts -o extracted.dts /proc/device-tree
