[PATCH v1 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 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.
