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 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 && 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.
