ARM: OMAP2: Powerdomain: Add base OMAP2/3 powerdomain code
This patch creates an interface to the powerdomain registers in the
PRM/CM modules on OMAP2/3. This interface is intended to be used by
PM code, e.g., pm.c; not by device drivers directly.
Each powerdomain will be defined in later patches as static
structures. Also defined are dependencies between powerdomains,
used for adding and removing PM_WKDEP and CM_SLEEPDEP bits. The
powerdomain structures are linked into a list at boot by
pwrdm_register(), similar to the OMAP clock code.
The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_POWERDOMAIN, which
when enabled will emit verbose debug messages via pr_debug().
