REF->v1:
 * Modelled as pincontrol as most of its configuration is intended to be
   static.
 * Updated reg size in example.

+description: |
+  The output pins of the general PWM timer (GPT) can be disabled by using
+  the port output enabling function for the GPT (POEG). Specifically,
+  either of the following ways can be used.
+  * Input level detection of the GTETRGA to GTETRGD pins.
+  * Output-disable request from the GPT.
+  * Register settings.
