* Some hardware implementations gracefully handle this case and allow a
* zero divisor by not modifying their input clock
* (divide by one / bypass).
+ * CLK_DIVIDER_HIWORD_MASK - The divider settings are only in lower 16-bit
+ * of this register, and mask of divider bits are in higher 16-bit of this
+ * register. While setting the divider bits, higher 16-bit should also be
+ * updated to indicate changing divider bits.
+ * CLK_DIVIDER_ROUND_CLOSEST - Makes the best calculated divider to be rounded
+ * to the closest integer instead of the up one.
