  21 * This file contains all of the powerdomains that have some element
  22 * of software control for the OMAP24xx and OMAP34xx chips.

  24 * This is not an exhaustive listing of powerdomains on the chips; only
  25 * powerdomains that can be controlled in software.

  29 * The names for the DSP/IVA2 powerdomains are confusing.
  30 *
  31 * Most OMAP chips have an on-board DSP.
  32 *
  33 * On the 2420, this is a 'C55 DSP called, simply, the DSP.  Its
  34 * powerdomain is called the "DSP power domain."  On the 2430, the
  35 * on-board DSP is a 'C64 DSP, now called (along with its hardware
  36 * accelerators) the IVA2 or IVA2.1.  Its powerdomain is still called
  37 * the "DSP power domain." On the 3430, the DSP is a 'C64 DSP like the
  38 * 2430, also known as the IVA2; but its powerdomain is now called the
  39 * "IVA2 power domain."
  40 *
  41 * The 2420 also has something called the IVA, which is a separate ARM
  42 * core, and has nothing to do with the DSP/IVA2.
  43 *
  44 * Ideally the DSP/IVA2 could just be the same powerdomain, but the PRCM
  45 * address offset is different between the C55 and C64 DSPs.
