-SLIM(Serial Low Power Interchip Media Bus) bus
-
-SLIMbus is a 2-wire bus, and is used to communicate with peripheral
-components like audio-codec.
-
-Required property for SLIMbus controller node:
-- compatible - name of SLIMbus controller
-
-Child nodes:
-Every SLIMbus controller node can contain zero or more child nodes
-representing slave devices on the bus. Every SLIMbus slave device is
-uniquely determined by the enumeration address containing 4 fields:
-Manufacturer ID, Product code, Device index, and Instance value for
-the device.
-If child node is not present and it is instantiated after device
-discovery (slave device reporting itself present).
-
-In some cases it may be necessary to describe non-probeable device
-details such as non-standard ways of powering up a device. In
-such cases, child nodes for those devices will be present as
-slaves of the SLIMbus controller, as detailed below.
-
-Required property for SLIMbus child node if it is present:
-- reg - Should be ('Device index', 'Instance ID') from SLIMbus
- Enumeration Address.
- Device Index Uniquely identifies multiple Devices within
- a single Component.
- Instance ID Is for the cases where multiple Devices of the
- same type or Class are attached to the bus.
-
-- compatible -"slimMID,PID". The textual representation of Manufacturer ID,
- Product Code, shall be in lower case hexadecimal with leading
- zeroes suppressed
-
-Optional property for SLIMbus child node if it is present:
-- slim-ifc-dev - Should be phandle to SLIMBus Interface device.
- Required for devices which deal with streams.
