13 Apple SoCs have various co-processors required for certain
14 peripherals to work (NVMe, display controller, etc.). This
15 driver adds support for the mailbox controller used to
16 communicate with those.
18 Say Y here if you have an Apple SoC.

23 depends on ARCH_APPLE || COMPILE_TEST
26 Apple SoCs such as the M1 come with various co-processors running
27 their proprietary RTKit operating system. This option enables support
28 for the protocol library used to communicate with those. It is used
29 by various client drivers.
31 Say 'y' here if you have an Apple SoC.
34 tristate "Apple SART DMA address filter"
35 depends on ARCH_APPLE || COMPILE_TEST
38 Apple SART is a simple DMA address filter used on Apple SoCs such
39 as the M1. It is usually required for the NVMe coprocessor which does
40 not use a proper IOMMU.
42 Say 'y' here if you have an Apple SoC.
