linux-kernel@vger.kernel.org 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.
