12*4882a593Smuzhiyun  * The names for the DSP/IVA2 powerdomains are confusing.
13*4882a593Smuzhiyun  *
14*4882a593Smuzhiyun  * Most OMAP chips have an on-board DSP.
15*4882a593Smuzhiyun  *
16*4882a593Smuzhiyun  * On the 2420, this is a 'C55 DSP called, simply, the DSP.  Its
17*4882a593Smuzhiyun  * powerdomain is called the "DSP power domain."  On the 2430, the
18*4882a593Smuzhiyun  * on-board DSP is a 'C64 DSP, now called (along with its hardware
19*4882a593Smuzhiyun  * accelerators) the IVA2 or IVA2.1.  Its powerdomain is still called
20*4882a593Smuzhiyun  * the "DSP power domain." On the 3430, the DSP is a 'C64 DSP like the
21*4882a593Smuzhiyun  * 2430, also known as the IVA2; but its powerdomain is now called the
22*4882a593Smuzhiyun  * "IVA2 power domain."
23*4882a593Smuzhiyun  *
24*4882a593Smuzhiyun  * The 2420 also has something called the IVA, which is a separate ARM
25*4882a593Smuzhiyun  * core, and has nothing to do with the DSP/IVA2.
26*4882a593Smuzhiyun  *
27*4882a593Smuzhiyun  * Ideally the DSP/IVA2 could just be the same powerdomain, but the PRCM
28*4882a593Smuzhiyun  * address offset is different between the C55 and C64 DSPs.
