7748 | * requirements for runtime PM. When these conditions are met, we manually do | |
7749 | * the other conditions: disable the interrupts, clocks and switch LCPLL refclk | |
7750 | * to Fclk. If we're in PC8+ and we get an non-hotplug interrupt, we can hard | |
7751 | * hang the machine. | |
7752 | * | |
7753 | * When we really reach PC8 or deeper states (not just when we allow it) we lose | |
7754 | * the state of some registers, so when we come back from PC8+ we need to | |
7755 | * restore this state. We don't get into PC8+ if we're not in RC6, so we don't | |
7756 | * need to take care of the registers kept by RC6. Notice that this happens even | |
7757 | * if we don't put the device in PCI D3 state (which is what currently happens | |
7758 | * because of the runtime PM support). | |
7759 | * | |
