| 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. |
