[DRIVER] Add support for SLB 9673 TPM2.0 (!56) · Merge requests · Clea OS / bsp / mediatek / linux-seco-mtk · GitLab

Oleksii Kutuzov requested to merge YT-383-e-58-tpm-support into seco_v5.15_v24.0 Mar 19, 2025

This adds the driver for I2C TPM. The universal I2C TPM 2.0 driver was introduced in kernel 6.0 and thus needed to be backported to 5.15.
The patch was found on Infineon's forum https://community.infineon.com/t5/OPTIGA-TPM/Does-the-SLB9673-compatibility-with-SLB9670-on-kernel-I2C-driver/m-p/381124#M183
Cherry-picked the upstream commits and applied the patch.

Also adjusted the device tree node to work with updated driver.
