  33 * The CPU PLLs are actually NP clocks, with P being /1 or /4. However
  34 * P should only be used for output frequencies lower than 228 MHz.
  35 * Neither mainline Linux, U-boot, nor the vendor BSPs use these.
  36 *
  37 * For now we can just model it as a multiplier clock, and force P to /1.
