TX1 SPI1 is disabled in JetPack4.2.2

Hello.

I want to use SPI1 in TX1 + JetPack4.2.2.

When TX1 + JetPack3.3. I edited devicetree and enabled SPI1.
https://elinux.org/Jetson/TX1_SPI

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>;
    };
};

However, I edit the device tree, TX1 + JetPack 4.2.2 does not enable SPI1.
(C:CNF 00->enable , 1f->disable)

$ sudo cat /sys/kernel/debug/tegra_gpio
Name:Bank:Port CNF OE OUT IN INT_STA INT_ENB INT_LVL
 A: 0:0 20 00 00 20 00 00 000000
 B: 0:1 0f 00 00 00 00 00 000000
 C: 0:2 <b>1f</b> 00 00 18 00 00 000000
 D: 0:3 00 00 00 00 00 00 000000
 E: 1:0 70 00 00 40 00 00 000000
 F: 1:1 00 00 00 00 00 00 000000

Next, I confirmed that it can be supported by modifying the cfg file as in TX2 + JetPack4.2.1.
https://elinux.org/Jetson/TX2_SPI

But,the pinmux file is not found in TX1 + Jetpack4.2.2
/bootloader/t210ref/BCT/

Is there any way to enable SPI1 with TX1 + JetPack4.2.2?
