  15  * The names for the DSP/IVA2 powerdomains are confusing.
  16  *
  17  * Most OMAP chips have an on-board DSP.
  18  *
  19  * On the 2420, this is a 'C55 DSP called, simply, the DSP.  Its
  20  * powerdomain is called the "DSP power domain."  On the 2430, the
  21  * on-board DSP is a 'C64 DSP, now called (along with its hardware
  22  * accelerators) the IVA2 or IVA2.1.  Its powerdomain is still called
  23  * the "DSP power domain." On the 3430, the DSP is a 'C64 DSP like the
  24  * 2430, also known as the IVA2; but its powerdomain is now called the
  25  * "IVA2 power domain."
  26  *
  27  * The 2420 also has something called the IVA, which is a separate ARM
  28  * core, and has nothing to do with the DSP/IVA2.
  29  *
  30  * Ideally the DSP/IVA2 could just be the same powerdomain, but the PRCM
  31  * address offset is different between the C55 and C64 DSPs.
