SPI TPM module support fail on jetpack 5.0.2/5.1 on jetson xavier agx

Autonomous Machines Jetson & Embedded Systems Jetson AGX Xavier

Once a fresh jetpack is installed, we followed the below steps on the Jetson
after configuring the kernel with the following configs
CONFIG_TCG_TPM=y
CONFIG_TCG_TIS_CORE=y
CONFIG_TCG_TIS_SPI=y

  1. run “sudo /opt/nvidia/jetson-io/jetson-io.py” and configure the 40-pin header for SPI1 pins and then save.

  2. use dtc to convert from dtb to dts the dtb file specified in FDT in /boot/extlinux/extlinux.conf

  3. once converted to dts, update the following to the dts file

    spi@3210000 {
         compatible = "nvidia,tegra186-spi";
         reg = <0x00 0x3210000 0x00 0x10000>;
         interrupts = <0x00 0x24 0x04>;
         #address-cells = <0x01>;
         #size-cells = <0x00>;
         iommus = <0x02 0x20>;
         dma-coherent;
         dmas = <0x24 0x0f 0x24 0x0f>;
         dma-names = "rx\0tx";
         spi-max-frequency = <0x3dfd240>;
         nvidia,clk-parents = "pll_p\0clk_m";
         clocks = <0x04 0x87 0x04 0x66 0x04 0x0e>;
         clock-names = "spi\0pll_p\0clk_m";
         resets = <0x04 0x5b>;
         reset-names = "spi";
         status = "okay";
         phandle = <0x2f7>;

         prod-settings {

                 prod_c_cs0 {
                         prod = <0x04 0xfff 0x11>;
                 };
         };

         slb9670@0 {
                 compatible = "tcg,tpm_tis-spi";
                 reg = <0x0>;
                 #address-cells = <1>;
                 #size-cells = <0>;
                 spi-max-frequency = <5000000>;
                 status = "okay";
                 controller-data {
                         nvidia,enable-hw-based-cs;
                 };
         };

/*
spi@1 {
compatible = “tegra-spidev”;
reg = <0x1>;

  1. use dtc again to convert dts to dtb and update the FDT filename in /boot/extlinux/extlinux.conf to the updated dtb file
