SLIMbus is a 2-wire implementation, which is used to communicate with peripheral components like audio-codec. SLIMbus uses Time-Division-Multiplexing to accommodate multiple data channels, and control channel. Control channel has messages to do device-enumeration, messages to send/receive control-data to/from slimbus devices, messages for port/channel management, and messages to do bandwidth allocation. Framework is introduced to support multiple instances of the bus (1 controller per bus), and multiple slave devices per controller. SPI and I2C frameworks, and comments from last time when I submitted the patches were referred-to while working on this framework. These patchsets introduce device-management, OF helpers, and messaging APIs for SLIMbus. Framework patches to do channel, port and bandwidth management are work-in-progress and will be sent out soon. These patchsets were tested on Qualcomm Snapdragon processor board using a controller driver, and a slimbus-dev module. This driver and module will be sent out after the framework patches mentioned above.
