12 * The names for the DSP/IVA2 powerdomains are confusing.
13 *
14 * Most OMAP chips have an on-board DSP.
15 *
16 * On the 2420, this is a 'C55 DSP called, simply, the DSP. Its
17 * powerdomain is called the "DSP power domain." On the 2430, the
18 * on-board DSP is a 'C64 DSP, now called (along with its hardware
19 * accelerators) the IVA2 or IVA2.1. Its powerdomain is still called
20 * the "DSP power domain." On the 3430, the DSP is a 'C64 DSP like the
21 * 2430, also known as the IVA2; but its powerdomain is now called the
22 * "IVA2 power domain."
23 *
24 * The 2420 also has something called the IVA, which is a separate ARM
25 * core, and has nothing to do with the DSP/IVA2.
26 *
27 * Ideally the DSP/IVA2 could just be the same powerdomain, but the PRCM
28 * address offset is different between the C55 and C64 DSPs.
