19 * This file contains all of the powerdomains that have some element
20 * of software control for the OMAP24xx and OMAP34XX chips.
24 * This is not an exhaustive listing of powerdomains on the chips; only
25 * powerdomains that can be controlled in software.
27 * A useful validation rule for struct powerdomain:
28 * Any powerdomain referenced by a wkdep_srcs or sleepdep_srcs array
29 * must have a dep_bit assigned. So wkdep_srcs/sleepdep_srcs are really
30 * just software-controllable dependencies. Non-software-controllable
31 * dependencies do exist, but they are not encoded below (yet).
33 * 24xx does not support programmable sleep dependencies (SLEEPDEP)
38 * The names for the DSP/IVA2 powerdomains are confusing.
40 * Most OMAP chips have an on-board DSP.
42 * On the 2420, this is a 'C55 DSP called, simply, the DSP. Its
43 * powerdomain is called the "DSP power domain." On the 2430, the
44 * on-board DSP is a 'C64 DSP, now called the IVA2 or IVA2.1. Its
45 * powerdomain is still called the "DSP power domain." On the 3430,
46 * the DSP is a 'C64 DSP like the 2430, also known as the IVA2; but
47 * its powerdomain is now called the "IVA2 power domain."
49 * The 2420 also has something called the IVA, which is a separate ARM
50 * core, and has nothing to do with the DSP/IVA2.
52 * Ideally the DSP/IVA2 could just be the same powerdomain, but the PRCM
53 * address offset is different between the C55 and C64 DSPs.
55 * The overly-specific dep_bit names are due to a bit name collision
56 * with CM_FCLKEN_{DSP,IVA2}. The DSP/IVA2 PM_WKDEP and CM_SLEEPDEP shift
57 * value are the same for all powerdomains: 2
61 * XXX should dep_bit be a mask, so we can test to see if it is 0 as a
63 * XXX encode hardware fixed wakeup dependencies -- esp. for 3430 CORE
