Subject: [PATCH] overlays: Make mcp342x run-time compatible
|
|
|
|
The order of processing of run-time overlays differs from that done by
|
|
the firmware. This means that certain parameter processing techniques
|
|
are not compatible with run-time use. The mcp342x overlay is one such
|
|
overlay, but it is easy to change the implementation without changing
|
|
the interface.
|
|
|
