Subject: [RFC PATCH 0/3] mailbox: hisilicon: add mailbox driver
Date: Mon, 3 Aug 2015 09:13:07 +0800 [thread overview]
Message-ID: <1438564390-28111-1-git-send-email-leo.yan@linaro.org> (raw)
This patch series is to implement Hisilicon's mailbox driver and enable
the mailbox controller on Hi6220.
The Hisilicon mailbox supports up to 32 channels. Each channel is
unidirectional with a maximum message size of 8 words. I/O is performed
using register access (there is no DMA) and the cell raises an interrupt
when messages are received.
For easily extending for Hisilicon series SoCs (SoCs may have difference
for register's definition with each other), so firstly implement common
mailbox driver; this common mailbox driver provides three mainly
functionality:
- help register channels into framework;
- hook low level callback functions for register's operations;
- Enhance rx channel's message queue, which is based on the code in
drivers/mailbox/omap-mailbox.c.
Base on this common driver, also has enabled Hi6220 mailbox controller.
