Slim?
SLIMbus is MIPI alliance specification. Since word "bus" is part of the specification, I thought it will be good to keep it that way. The specification is available to all MIPI members. Some more info here: http://mipi.org/specifications/serial-low-power-inter-chip-media-bus-slimbussm-specification

+and the messages can be of unicast and broadcast type. E.g. reading/writing +device specific values is typically a unicast message. A data channel +reconfiguration sequence is announced to all devices using a broadcast message.Unicast messages are seen by all devices?
I was trying to give example of each type of both message. I will reword it to be more clear.

+Slimbus specification has different types of device classifications based on +their capabilities.I'm trying to figure out if that sentence conveys any information at all.
I will reword this to say: "has following type of device classifications based on capabilities:".
So each slimbus has 1 manager device that enumerates configures, and allocates channels for the other devices on the bus. The rest are "framer" devices that transmit data packets?
Typically there is 1 framer per bus, but if there are multiple framers then manager is responsible for doing handoff between framers.
However, I expect some example code would be far more useful than this document...
Please refer to slimbus.c for slimbus framework. Thank you for your comments. I will address all the comments in the next patch. Regards Sagar Sent by an employee of the Qualcomm Innovation Center, Inc. The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum.
