| 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 | |
| 55ed9694 PW |
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." | |
| 9717100f PW |
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. | |
