0012  * The names for the DSP/IVA2 powerdomains are confusing.
0013  *
0014  * Most OMAP chips have an on-board DSP.
0015  *
0016  * On the 2420, this is a 'C55 DSP called, simply, the DSP.  Its
0017  * powerdomain is called the "DSP power domain."  On the 2430, the
0018  * on-board DSP is a 'C64 DSP, now called (along with its hardware
0019  * accelerators) the IVA2 or IVA2.1.  Its powerdomain is still called
0020  * the "DSP power domain." On the 3430, the DSP is a 'C64 DSP like the
0021  * 2430, also known as the IVA2; but its powerdomain is now called the
0022  * "IVA2 power domain."
0023  *
0024  * The 2420 also has something called the IVA, which is a separate ARM
0025  * core, and has nothing to do with the DSP/IVA2.
0026  *
0027  * Ideally the DSP/IVA2 could just be the same powerdomain, but the PRCM
0028  * address offset is different between the C55 and C64 DSPs.
