ARM: OMAP2: Clockdomain: Add base OMAP2/3 clockdomain code
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().
