mailbox: Explicitly include correct DT includes The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

mailbox: Hi3660: Fixup mailbox state machine malfunction issue Current mailbox driver of Hi3660 release the mailbox directly before sending a new message which may cause last message lost and next message sending doesn't take effect actually. This patch fixs this issue by following the right progress below, each time before sending a message, mailbox driver will check whether the mailbox is in ready state, if last message has been acknowledged, the mailbox driver will clear the ack state to turn the mailbox to ready state again.

mailbox: Add support for Hi3660 mailbox Hi3660 mailbox controller is used to send message within multiple processors, MCU, HIFI, etc. It supports 32 mailbox channels and every channel can only be used for single transferring direction. Once the channel is enabled, it needs to specify the destination interrupt and acknowledge interrupt, these two interrupt vectors are used to create the connection between the mailbox and interrupt controllers. The data transferring supports two modes, one is named as "automatic acknowledge" mode so after send message the kernel doesn't need to wait for acknowledge from remote and directly return; there have another mode is to rely on handling interrupt for acknowledge. This commit is for initial version driver, which only supports "automatic acknowledge" mode to support CPU clock, which is the only one consumer to use mailbox and has been verified. Later may enhance this driver for interrupt mode (e.g. for supporting HIFI).
