  26 * The CPU PLL is actually NP clock, with P being /1, /2 or /4. However
  27 * P should only be used for output frequencies lower than 288 MHz.
  28 *
  29 * For now we can just model it as a multiplier clock, and force P to /1.
  30 *
  31 * The M factor is present in the register's description, but not in the
  32 * frequency formula, and it's documented as "M is only used for backdoor
  33 * testing", so it's not modelled and then force to 0.
