The PMGR block in Apple SoCs provides high-level power state
controls for SoC devices. This driver manages them through the
generic power domain framework, and also provides reset support.

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.

help
Apple SoCs such as the M1 come with various co-processors running
their proprietary RTKit operating system. This option enables support
for a generic co-processor that does not implement any additional
in-band communications. It can be used for testing purposes, or for
coprocessors such as MTP that communicate over a different interface.
Say 'y' here if you have an Apple SoC.

help
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.

DockChannel is a simple FIFO used on Apple SoCs for debug and inter-processor
communications.
