- * CLKDM_NO_AUTODEPS: Prevent "autodeps" from being added/removed from this

- * 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
- * the force-wakeup mode, then it will be used whenever a clock or
- * IP block inside the clockdomain is active, rather than the
- * HW_AUTO mode.
