Enabling SPI and setting pinmux on JetPack 4.2.2 (L4T 32.2 and higher) not working

I’m trying to enable SPI1 on header J41. I tried few different topics to get this done, but none of them seems to solve the problem.
Here is my DT:

gpio@6000d000 {
    spi1_pins: spi1 {
        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
            >;
            label = "SPI1_MOSI", "SPI1_MISO", "SPI1_SCK", 
               "SPI1_CS0", "SPI1_CS1";
            line-name = "spi1-line";
            };

spi@7000d400 {
    status = "okay";
	spidev {
	    #address-cells = <1>;
            #size-cells = <0>;
            compatible = "spidev";
            reg = <0>;
            spi-max-frequency = <500000>;
            //controller-data {
            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>;
            //};
    };
};

According to this topic:

and this dts:

everything is seems to be done right, but looking at GPIO settings it looks like it’s not set:

Is there any change for setting pinmux in kernel? Or this should be done now in different way (cboot?)
