+ * CPU0 and CPU1 LPRM modules.
+ * CPU0, CPU1 and MPUSS each have there own power domain and

+ *
+ * The CPU0 and CPU1 can't support Closed switch Retention (CSWR)
+ * because the mode is not supported by hw constraints of dormant
+ * mode. While waking up from the dormant mode, a reset signal
+ * to the Cortex-A9 processor must be asserted by the external
+ * power controller.
+ *
+ * With architectural inputs and hardware recommendations, only
+ * below modes are supported from power gain vs latency point of view.

+ * OFF OFF CSWR
+ * OFF OFF OSWR
+ * OFF OFF OFF(Device OFF *TBD)
+ * ----------------------------------------------

+ *
+ * Introduction
+ * ------------
+ * One way to view an OMAP SoC is as a collection of largely unrelated
+ * IP blocks connected by interconnects. The IP blocks include
+ * devices such as ARM processors, audio serial interfaces, UARTs,
+ * etc. Some of these devices, like the DSP, are created by TI;
+ * others, like the SGX, largely originate from external vendors. In
+ * TI's documentation, on-chip devices are referred to as "OMAP
+ * modules." Some of these IP blocks are identical across several
+ * OMAP versions. Others are revised frequently.
+ *
+ * These OMAP modules are tied together by various interconnects.
+ * Most of the address and data flow between modules is via OCP-based
+ * interconnects such as the L3 and L4 buses; but there are other
+ * interconnects that distribute the hardware clock tree, handle idle
+ * and reset signaling, supply power, and connect the modules to
+ * various pads or balls on the OMAP package.
+ *
+ * OMAP hwmod provides a consistent way to describe the on-chip
+ * hardware blocks and their integration into the rest of the chip.
+ * This description can be automatically generated from the TI
+ * hardware database. OMAP hwmod provides a standard, consistent API
+ * to reset, enable, idle, and disable these hardware blocks. And
+ * hwmod provides a way for other core code, such as the Linux device
+ * code or the OMAP power management and address space mapping code,
+ * to query the hardware database.
+ *
+ * Using hwmod
+ * -----------
+ * Drivers won't call hwmod functions directly. That is done by the
+ * omap_device code, and in rare occasions, by custom integration code
+ * in arch/arm/ *omap*. The omap_device code includes functions to
+ * build a struct platform_device using omap_hwmod data, and that is
+ * currently how hwmod data is communicated to drivers and to the
+ * Linux driver model. Most drivers will call omap_hwmod functions only
+ * indirectly, via pm_runtime*() functions.
+ *
+ * From a layering perspective, here is where the OMAP hwmod code
+ * fits into the kernel software stack:
+ *
+ * +-------------------------------+
+ * | Device driver code |
+ * | (e.g., drivers/) |
+ * +-------------------------------+
+ * | Linux driver model |
+ * | (platform_device / |
+ * | platform_driver data/code) |
+ * +-------------------------------+
+ * | OMAP core-driver integration |
+ * |(arch/arm/mach-omap2/devices.c)|
+ * +-------------------------------+
+ * | omap_device code |
+ * | (../plat-omap/omap_device.c) |
+ * +-------------------------------+
+ * ----> | omap_hwmod code/data | <-----
+ * | (../mach-omap2/omap_hwmod*) |
+ * +-------------------------------+
+ * | OMAP clock/PRCM/register fns |
+ * | ({read,write}l_relaxed, clk*) |
+ * +-------------------------------+
+ *
+ * Device drivers should not contain any OMAP-specific code or data in
+ * them. They should only contain code to operate the IP block that
+ * the driver is responsible for. This is because these IP blocks can
+ * also appear in other SoCs, either from TI (such as DaVinci) or from
+ * other manufacturers; and drivers should be reusable across other
+ * platforms.
+ *
+ * The OMAP hwmod code also will attempt to reset and idle all on-chip
+ * devices upon boot. The goal here is for the kernel to be
+ * completely self-reliant and independent from bootloaders. This is
+ * to ensure a repeatable configuration, both to ensure consistent
+ * runtime behavior, and to make it easier for others to reproduce
+ * bugs.
+ *
+ * OMAP module activity states
+ * ---------------------------
+ * The hwmod code considers modules to be in one of several activity
+ * states. IP blocks start out in an UNKNOWN state, then once they
+ * are registered via the hwmod code, proceed to the REGISTERED state.
+ * Once their clock names are resolved to clock pointers, the module
+ * enters the CLKS_INITED state; and finally, once the module has been
+ * reset and the integration registers programmed, the INITIALIZED state
+ * is entered. The hwmod code will then place the module into either
+ * the IDLE state to save power, or in the case of a critical system
+ * module, the ENABLED state.
+ *
+ * OMAP core integration code can then call omap_hwmod*() functions
+ * directly to move the module between the IDLE, ENABLED, and DISABLED
+ * states, as needed. This is done during both the PM idle loop, and
+ * in the OMAP core integration code's implementation of the PM runtime
+ * functions.

+ * the MPU if left active.

+ * block data and interconnect data is available to the hwmod code, it

+ * drivers are either shut down or enabled after the drivers have

+ * when module is enabled, rather than the default, which is to
+ * enable autoidle
+ * HWMOD_SET_DEFAULT_CLOCKACT: program CLOCKACTIVITY bits at startup
+ * HWMOD_NO_IDLEST: this module does not have idle status - this is the case
+ * only for few initiator modules on OMAP2 & 3.
+ * HWMOD_CONTROL_OPT_CLKS_IN_RESET: Enable all optional clocks during reset.
+ * This is needed for devices like DSS that require optional clocks enabled
+ * in order to complete the reset. Optional clocks will be disabled
+ * again after the reset.
+ * HWMOD_16BIT_REG: Module has 16bit registers
+ * HWMOD_EXT_OPT_MAIN_CLK: The only main functional clock source for
+ * this IP block comes from an off-chip source and is not always
+ * enabled. This prevents the hwmod code from being able to
+ * enable and reset the IP block early. XXX Eventually it should
+ * be possible to query the clock framework for this information.
+ * HWMOD_BLOCK_WFI: Some OMAP peripherals apparently don't work
+ * correctly if the MPU is allowed to go idle while the
+ * peripherals are active. This is apparently true for the I2C on
+ * OMAP2420, and also the EMAC on AM3517/3505. It's unlikely that
+ * this is really true -- we're probably not configuring something
+ * correctly, or this is being abused to deal with some PM latency
+ * issues -- but we're currently suffering from a shortage of
+ * folks who are able to track these issues down properly.
+ * HWMOD_FORCE_MSTANDBY: Always keep MIDLEMODE bits cleared so that device
+ * is kept in force-standby mode. Failing to do so causes PM problems
+ * with musb on OMAP3630 at least. Note that musb has a dedicated register
+ * to control MSTANDBY signal when MIDLEMODE is set to force-standby.
+ * HWMOD_SWSUP_SIDLE_ACT: omap_hwmod code should manually bring the module
+ * out of idle, but rely on smart-idle to the put it back in idle,
+ * so the wakeups are still functional (Only known case for now is UART)
+ * HWMOD_RECONFIG_IO_CHAIN: omap_hwmod code needs to reconfigure wake-up
+ * events by calling _reconfigure_io_chain() when a device is enabled
+ * or idled.
+ * HWMOD_OPT_CLKS_NEEDED: The optional clocks are needed for the module to
+ * operate and they need to be handled at the same time as the main_clk.
+ * HWMOD_NO_IDLE: Do not idle the hwmod at all. Useful to handle certain
+ * IPs like CPSW on DRA7, where clocks to this module cannot be disabled.
+ * HWMOD_CLKDM_NOAUTO: Allows the hwmod's clockdomain to be prevented from
+ * entering HW_AUTO while hwmod is active. This is needed to workaround
+ * some modules which don't function correctly with HW_AUTO. For example,
+ * DCAN on DRA7x SoC needs this to workaround errata i893.

+ * The if the DPLL is going to AutoIdle. It seems like the DPLL may be back on

+ * oscillator was stopped, a timing bug exists where a non-stabilized 12MHz
+ * clock can pass into the PRCM can cause problems at DSP and IVA.
+ * To work around this the code will switch to the 32kHz source prior to sleep.
+ * Post sleep we will shift back to using the DPLL. Apparently,

+ * @cpu_state : contains context save state (r0)

+ * 3 - CPUx L1 and logic lost + GIC + L2 lost: MPUSS OFF
+ * @return: This function never returns for CPU OFF and DORMANT power states.
+ * Post WFI, CPU transitions to DORMANT or OFF power state and on wake-up
+ * from this follows a full CPU reset path via ROM code to CPU restore code.
+ * The restore function pointer is stored at CPUx_WAKEUP_NS_PA_ADDR_OFFSET.
+ * It returns to the caller for CPU INACTIVE and ON power states or in case
+ * CPU failed to transition to targeted OFF/DORMANT state.
+ *
+ * omap4_finish_suspend() calls v7_flush_dcache_all() which doesn't save
