SLIMbus (Serial Low Power Interchip Media Bus) is a specification developed by MIPI (Mobile Industry Processor Interface) alliance. 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. The framework supports multiple instances of the bus (1 controller per bus), and multiple slave devices per controller. This patch does device enumeration, logical address assignment, informing device when the device reports present/absent etc. Reporting present may need the driver to do the needful (e.g. turning on voltage regulators powering the device). So probe is called if the device is added to board-info list for a controller. Additionally device is probed when it reports present if that device doesn't need any such steps mentioned above.

I think I was not as fast as you sent the v2 :-) However my comments on v1 patcset mostly still applies to v2 as well. --srini -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
