No TPM information in i.MX Linux Release Note.

Hello community,

I hope to know about support status of Timer/PWM module for i.MX93.

In Table 6 ofi.MX Linux Reference Manual(RM00293) has driver source code "timer-imx-tpm.c".

But no status information in i.MX Linux Release Notes(RN00210).

I would like the TPM support status to be added to the Release Notes.

Best regards,

Ishii.

What do you mean "support status of Timer/PWM module"?

As I know, we have two drivers for tpm module, timer-imx-tpm.c and pwm-imx-tpm.c.

The timer-imx-tpm.c will use tpm as a timer, while pwm-imx-tpm.c will use tpm as a pwm.

Both drivers are OK now.

Thanks!

Thank you for your reply.
How about capture function, count between edge to edge of external input signal?

Best regards,

AFAIK, the capture function is not supported yet.

Thank you for your quick reply.

I would like information about this support status to be included in the i.MX Linux Release Notes.

Best regards,
