12 Apple SoCs have various co-processors required for certain
13 peripherals to work (NVMe, display controller, etc.). This
14 driver adds support for the mailbox controller used to
15 communicate with those.

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

34 help
35 Apple SART is a simple DMA address filter used on Apple SoCs such
36 as the M1. It is usually required for the NVMe coprocessor which does
37 not use a proper IOMMU.
