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