Subject: [PATCH v2 0/3] mailbox: Add support for Hi3660 mailbox

From: Leo Yan <leo.yan@...aro.org>

Hi3660 mailbox controller is used to send message within multiple
processors, MCU, HIFI, etc. This patch series is to implement an
initial version for Hi3660 mailbox driver with "automatic
acknowledge" mode.

The patch set have been verified with Hi3660 stub clock driver, so
we can send message to MCU to execute CPU frequency scaling. This is
tested on 96boards Hikey960.

Changes from v1:
* Refactored structure definition according to Jassi's suggestion;
* Refactored and simplized mailbox driver with "automatic ack" mode;
* Refined commit logs to give background info for driver;
* Added document for DT binding;
* Added cover letter to track the changelog.
