Mailbox is used by the Rockchip CPU cores to communicate requests to MCU processor.
This driver is found on RK3368 SoCs.
The Mailbox module is a simple APB peripheral that allows both the Cortex-A53 MCU system to communicate by writing operation to generate interrupt. The registers are accessible by both CPU via APB interface.
Tested on RK3368 SDK board.
Changes in v1: - PATCH[1/3] doc: - As the Rob Herring comments, s/share/shared/ and specify the value of #mbox-cells. - Move the shared memory in mailbox, let's move the property the client driver in the future. - PATCH[2/3] driver: - The commit: %s/@/(num order). - Add the module authors to instead of the notes. - Add the COMPILE_TEST to auto compile test in Kconfig. - Let the chan_to_idx() trys to instead of rockchip_mbox_chan.idx. - Let's enable/disable the interrupt in startup/shutdown. - Move the share memory and tx buf into the client drivers. - PATCH[3/3] dts: - fix "processormZ"--> "processor",the miss-fingerboard. - Remove the shared memory in mailbox controller dtsi.
