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