|
|
* 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.
