Paul Walmsley | 006c7f1 | 2012-07-04 05:22:53 -0600 | [diff] [blame] | 29 | * CLKDM_ACTIVE_WITH_MPU: The PRCM guarantees that this clockdomain is |
| 30 | * active whenever the MPU is active. True for interconnects and |
| 31 | * the WKUP clockdomains. |
Paul Walmsley | b71c721 | 2012-09-23 17:28:28 -0600 | [diff] [blame] | 32 | * CLKDM_MISSING_IDLE_REPORTING: The idle status of the IP blocks and |
| 33 | * clocks inside this clockdomain are not taken into account by |
| 34 | * the PRCM when determining whether the clockdomain is idle. |
| 35 | * Without this flag, if the clockdomain is set to |
| 36 | * hardware-supervised idle mode, the PRCM may transition the |
| 37 | * enclosing powerdomain to a low power state, even when devices |
| 38 | * inside the clockdomain and powerdomain are in use. (An example |
| 39 | * of such a clockdomain is the EMU clockdomain on OMAP3/4.) If |
| 40 | * this flag is set, and the clockdomain does not support the |
| 41 | * force-sleep mode, then the HW_AUTO mode will be used to put the |
| 42 | * clockdomain to sleep. Similarly, if the clockdomain supports |
| 43 | * the force-wakeup mode, then it will be used whenever a clock or |
| 44 | * IP block inside the clockdomain is active, rather than the |
| 45 | * HW_AUTO mode. |
