- menu "Mailbox Controller Support"
- config DM_MAILBOX
- bool "Enable mailbox controllers using Driver Model"
- depends on DM && OF_CONTROL
- help
- Enable support for the mailbox driver class. Mailboxes provide the
- ability to transfer small messages and/or notifications from one
- CPU to another CPU, or sometimes to dedicated HW modules. They form
- the basis of a variety of inter-process/inter-CPU communication
- protocols.
- config APPLE_MBOX
- bool "Enable Apple IOP controller support"
- depends on DM_MAILBOX && ARCH_APPLE
- default y
- help
- Enable support for the mailboxes that provide a comminucation
- channel with Apple IOP controllers integrated on Apple SoCs.
- These IOP controllers are used to implement various functions
- such as the System Management Controller (SMC) and NVMe and this
- driver is required to get that functionality up and running.
- config SANDBOX_MBOX
- bool "Enable the sandbox mailbox test driver"
- depends on DM_MAILBOX && SANDBOX
- help
- Enable support for a test mailbox implementation, which simply echos
- back a modified version of any message that is sent.
- config TEGRA_HSP
- bool "Enable Tegra HSP controller support"
- depends on DM_MAILBOX && ARCH_TEGRA
- help
- This enables support for the NVIDIA Tegra HSP Hw module, which
- implements doorbells, mailboxes, semaphores, and shared interrupts.
- config STM32_IPCC
- bool "Enable STM32 IPCC controller support"
- depends on DM_MAILBOX && ARCH_STM32MP
- help
- This enables support for the STM32MP IPCC Hw module, which
- implements doorbells between 2 processors.
- config K3_SEC_PROXY
- bool "Texas Instruments K3 Secure Proxy Driver"
- depends on DM_MAILBOX && ARCH_K3
- help
- An implementation of Secure proxy slave driver for K3 SoCs from
- Texas Instruments. Secure proxy is a communication entity mainly
- used for communication between multiple processors with the SoC.
- Select this driver if your platform has support for this hardware
- block.
- config ZYNQMP_IPI
- bool "Xilinx ZynqMP IPI controller support"
- depends on DM_MAILBOX && (ARCH_ZYNQMP || ARCH_VERSAL || ARCH_VERSAL_NET)
- help
- This enables support for the Xilinx ZynqMP Inter Processor Interrupt
- communication controller.
