slimbus: Add SLIMbus bus type 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 adds support to basic silmbus core which includes support to SLIMbus type, slimbus device registeration and some basic data structures.

slimbus: qcom: Add Qualcomm Slimbus controller driver This controller driver programs manager, interface, and framer devices for Qualcomm's slimbus HW block. Manager component currently implements logical address setting, and messaging interface. Interface device reports bus synchronization information, and framer device clocks the bus from the time it's woken up, until clock-pause is executed by the manager device.
