How to enable TPM2.0 module in Xavier?

Hi Jerry:

I also reference SPI1 not work on Xavier , change the .cfg pinmux settings. And modify the dts as below:

	spi@c260000 {
		status = "okay";
		nvidia,clock-always-on;	
		slb9670: slb9670@0{
			compatible = "tcg,tpm_tis-spi";
			status = "okay";
			reg = <0x0>; /* CE0 */
			#address-cells = <1>;
			#size-cells = <0>;
			spi-max-frequency = <5000000>;
			nvidia,enable-hw-based-cs;
		};		
	};

Add “nvidia,clock-always-on;” description in dts file. The system got /dev/spidev0.0, but the tpm module can’t work too. Do you have any suggestion about this? Thanks!
