Checking the 5.15.72-2.2.0 kernel, I can find a TPM driver for the i.MX7ULP and i.MX8ULP. The documentation is here:</P><P><A href="https://github.com/nxp-imx/linux-imx/blob/lf-5.15.71-2.2.0/Documentation/devicetree/bindings/timer/nxp%2Ctpm-timer.yaml" target="_blank">https://github.com/nxp-imx/linux-imx/blob/lf-5.15.71-2.2.0/Documentation/devicetree/bindings/timer/nxp%2Ctpm-timer.yaml</A></P><P>So as far as I can see, there is currently no official support for TPM on this platform. Is the i.MX8ULP module compatible with the one in i.MX8QXP or will this require a completely new driver?</P><P>Any hint will be greatly appreciated!</P> Tue, 04 Apr 2023 15:16:02 GMT https://community.nxp.com/t5/i-MX-Processors/Linux-driver-for-Timer-PWM-Module-TPM-on-i-MX8QXP/m-p/1627763#M203724 laodzu 2023-04-04T15:16:02Z https://community.nxp.com/t5/i-MX-Processors/Linux-driver-for-Timer-PWM-Module-TPM-on-i-MX8QXP/m-p/1627830#M203729 <P>Hello!</P> <P>Theoretically the IMX7ULP and the IMX8QXP have the same TPM module, the only difference is the counter, in the IMX7ULP the counter is of 16-bit.
