> The Timer/PWM Module (TPM) supports input capture, output compare, and the
> generation of PWM signals to control electric motor and power management
> applications. The counter, compare and capture registers are clocked by an
> asynchronous clock that can remain enabled in low power modes. TPM can
> support global counter bus where one TPM drives the counter bus for the
> others, provided bit width is the same.
> 
> This patch only adds the timer support. PWM would be added later.

> v2->v3:

> v1->v2:
