+ * 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.
