| The PMGR block in Apple SoCs provides high-level power state | |
| controls for SoC devices. This driver manages miscellaneous | |
| power controls. | |
| Say 'y' here if you have a Pro/Max/Ultra Apple SoC. | |

| help | |
| Apple SoCs such as the M1 come with various co-processors running | |
| their proprietary RTKit operating system. This option enables support | |
| for the protocol library used to communicate with those. It is used | |
| by various client drivers. | |

| Apple SART is a simple DMA address filter used on Apple SoCs such | |
| as the M1. It is usually required for the NVMe coprocessor which does | |
| not use a proper IOMMU. | |
| Say 'y' here if you have an Apple SoC. | |
