H A Dslimbus.rst2 Linux kernel SLIMbus support
8 What is SLIMbus?
10 SLIMbus (Serial Low Power Interchip Media Bus) is a specification developed by
14 Currently, SLIMbus is used to interface between application processors of SoCs
15 (System-on-Chip) and peripheral components (typically codec). SLIMbus uses
24 A data channel is used for data-transfer between 2 SLIMbus devices. Data
29 SLIMbus specification has different types of device classifications based on
39 Each SLIMbus component has an interface device for monitoring physical layer.
41 Typically each SoC contains SLIMbus component having 1 manager, 1 framer device,
43 External peripheral SLIMbus component usually has 1 generic device (for
