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)
help
This enables support for the Xilinx ZynqMP Inter Processor Interrupt
communication controller.
