+title: NXP Low Power Timer/Pulse Width Modulation Module (TPM)
+
+maintainers:
+  - Dong Aisheng <aisheng.dong@nxp.com>
+
+description: |
+  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.
