[RFC PATCH 0/2] scpi: Add SCPI framework to handle vendors variants

Show all headers | View raw

Since the current SCPI implementation, based on [0]:
- is (at leat) JUNO specific
- does not specify a strong "standard"
- does not specify a strong MHU interface specification

SoC vendors could implement a variant with slight changes in message
indexes, new messages types, different messages data format or different MHU
communication scheme.

To keep the spirit of the SCPI interface, add a thin "register" layer to get
the ops from the parent node and switch the drivers using the ops to use
the new of_scpi_ops_get() call.
