[PATCH 0/3] mailbox: rockchip: Add mailbox driver for Rockchip platform

[Caesar Wang]

Mailbox is used by the Rockchip CPU cores to communicate
requests to MCU processorm.

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.
