+description: |
+ The Intel Keem Bay timer driver supports 1 free running counter and 8 timers.
+ Each timer is capable of generating inividual interrupt.
+ Both the features are enabled through the timer general config register.
+
+ The parent node represents the common general configuration details and
+ the child nodes represents the counter and timers.
