Subject: [PATCH] overlays: Fix mcp23017's addr parameter
|
|
|
|
The addr parameter of the mcp23017 overlay was broken by the addition
|
|
of the noints parameter; splitting the mcp node in two without also
|
|
modifying the second half from the addr parameter would cause the two
|
|
halves to separate. Change the implementation strategy to patch
|
|
fragment 2 (as was originally proposed). This will prevent the
|
|
overlay from being applied at runtime until the "dtoverlay" command
|
|
is improved, but the overlay already has this restriction due to
|
|
fragment 3 so this isn't a step backwards.
|
|
