SPIDEV at mt7620n

Hi everyone! I'm trying to add spidev device at Keenetic router with mt7620n SoC to test flash frequency and I'm to face a problem. spidev doesn't add in my system. I have seen how it is implemented already in rt5350_dlink_dwr-512-b.dts but it doesn't work.

mt7620n_zyxel_keenetic-lite-iii-a.dts 
....
&spi0 {
	status = "okay";

	flash@0 {
		compatible = "jedec,spi-nor";
		reg = <0>;
		spi-max-frequency = <48000000>;

		partitions {
			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;

			partition@0 {
				label = "U-Boot";
				reg = <0x0 0x30000>;
				read-only;
			};

			partition@30000 {
				label = "U-Config";
				reg = <0x30000 0x10000>;
			};

			factory: partition@40000 {
				label = "RF-EEPROM";
				reg = <0x40000 0x10000>;
				read-only;
			};

			partition@50000 {
				compatible = "denx,uimage";
				label = "firmware";
				reg = <0x50000 0x7a0000>;
			};

			partition@7f0000 {
				label = "Config";
				reg = <0x7f0000 0x10000>;
			};

			partition@0_1 {
				label = "Full";
				reg = <0x0 0x800000>;
			};
		};
	};
};

&spi1 {
	status = "okay";

	spidev@0 {
		#address-cells = <1>;
		#size-cells = <1>;
		compatible = "linux,spidev";
		reg = <0>;
		spi-max-frequency = <48000000>;
	};
};
...

Could help me, please to run it with spidev:)
