+ *
+ * CLKDM_NO_AUTODEPS: Prevent "autodeps" from being added/removed from this
+ *     clockdomain.  (Currently, this applies to OMAP3 clockdomains only.)
+ * CLKDM_ACTIVE_WITH_MPU: The PRCM guarantees that this clockdomain is
+ *     active whenever the MPU is active.  True for interconnects and
+ *     the WKUP clockdomains.
+ * CLKDM_MISSING_IDLE_REPORTING: The idle status of the IP blocks and
+ *     clocks inside this clockdomain are not taken into account by
+ *     the PRCM when determining whether the clockdomain is idle.
+ *     Without this flag, if the clockdomain is set to
+ *     hardware-supervised idle mode, the PRCM may transition the
+ *     enclosing powerdomain to a low power state, even when devices
+ *     inside the clockdomain and powerdomain are in use.  (An example
+ *     of such a clockdomain is the EMU clockdomain on OMAP3/4.)  If
+ *     this flag is set, and the clockdomain does not support the
+ *     force-sleep mode, then the HW_AUTO mode will be used to put the
+ *     clockdomain to sleep.  Similarly, if the clockdomain supports

+ * 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 IP block stays in this state until a PM runtime-based driver is

+ * blocks such as the MPU WDTIMER on kernels without WDTIMER drivers
+ * included, since the WDTIMER starts running on reset and will reset
+ * the MPU if left active.
+ *
+ * This post-setup mechanism is deprecated.  Once all of the OMAP
+ * drivers have been converted to use PM runtime, and all of the IP
+ * block data and interconnect data is available to the hwmod code, it

+ * when the driver first probes, then all remaining IP blocks without
+ * drivers are either shut down or enabled after the drivers have
+ * loaded.  However, this cannot take place until the above

+ * HWMOD_SET_DEFAULT_CLOCKACT: program CLOCKACTIVITY bits at startup
+ * HWMOD_NO_IDLEST: this module does not have idle status - this is the case

+ * 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

+ *     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.

+ * @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

+ * 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
