+  Return the input clock frequency to an IP Module.
+  This function reads the RCW bits and calculates the  PLL multiplier/divider
+  values to be applied to various IP modules.
+  If a module is disabled or doesn't exist on platform, then return zero.
+
+  @param[in]  BaseClock  Base clock to which PLL multiplier/divider values is
+                         to be applied.
+  @param[in]  ClockType  Variable of Type NXP_IP_CLOCK. Indicates which IP clock
+                         is to be retrieved.
+  @param[in]  Args       Variable argument list which is parsed based on
+                         ClockType. e.g. if the ClockType is NXP_I2C_CLOCK, then
+                         the second argument will be interpreted as controller
+                         number. e.g. if there are four i2c controllers in SOC,
+                         then this value can be 0, 1, 2, 3
+                         e.g. if ClockType is NXP_CORE_CLOCK, then second
+                         argument is interpreted as cluster number and third
+                         argument is interpreted as core number (within the
+                         cluster)
+
+  @return                Actual Clock Frequency. Return value 0 should be
+                         interpreted as clock not being provided to IP.
