This patch creates an interface to the clockdomain 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. The patch also adds clockdomain usecount tracking. This is intended to be called whenever the first clock in a clockdomain is enabled, or when the last enabled clock in a clockdomain is disabled. If the clockdomain is in software-supervised mode, the code will force-wakeup or force-sleep the clockdomain. If the clockdomain is in hardware-supervised mode, the first clock enable will add sleep and wakeup dependencies on a user-selectable set of parent domains (usually MPU & IVA2), and the disable will remove them. Each clockdomain will be defined in later patches as static structures. The clockdomain structures are linked into a list at boot by clkdm_register(), similar to the OMAP clock code. The patch adds a Kconfig option, CONFIG_OMAP_DEBUG_CLOCKDOMAIN, which when enabled will emit verbose debug messages via pr_debug().
