Hi, We have an Orin NX on a custom carrier board with a 2.0 TPM device communicating via SPI. Its my first time working with TPM and SPI driver and I have few question please: I read that the upstream tpm spi driver is good for this device but what about the device tree and kernel configuration…

[image] bsp_dev: following is the device tree modification instructions from the vendor documentation: Please just port this configuration to spi0: spi@3210000.
