| 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. |
