-	  The GDFS service will default to HIGH frequency until it receives
-	  a lower frequency request. The NRF2 clock controller drivers
-	  expect the clock to be initialized to their lowest frequency, so
-	  we need to send a request on init to align GDFS with the NRF2
-	  clock controller driver.
-
-	  This initial request can be disabled to prevent a potentially
-	  unnecessary HIGH -> LOW -> HIGH cycle given some module will
-	  request a HIGH frequency on init anyway.
