[PATCH v2 0/6] Mailbox: Provide support STi based platforms

From: Lee Jones
Date: Mon Jul 27 2015 - 05:44:43 EST


ST's platforms currently support a maximum of 5 Mailboxes, one for
each of the supported co-processors situated on the platform. Each
Mailbox is divided up into 4 instances which consist of 32 channels.
Messages are passed between the application and co-processors using
shared memory areas.

Also included in the set is an example Client which should be generic
enough to use as a testing environment for all Mailbox IPs which use
shared memory to pass messages. With a small change, it should also
be able to test more extravagant implementations too.

v1 => v2:
- New MACRO() to obtain base address for a given instance
- Move locking into the structure it protects
- Stop checking for 'ready' state when sending data
- Don't clear channel data (that belongs to the API)
- #define register offsets instead of providing via pdata
- Register driver with module_platform_driver()

Lee Jones (6):
