Subject: [PATCH 1090/1135] dtoverlays: Fix noints mode of mcp23017
|
||
|
|
|
||
|
|
noints mode disables 2 fragments that configure a GPIO to
|
||
|
|
be used for the interrupt line from the MCP23017, but fails
|
||
|
|
to remove the pinctrl-0 reference or pinctrl-names.
|
||
|
|
It therefore fails to load due to an invalid phandle.
|
||
|
|
|
||
|
|
Move the pinctrl-0 and pinctrl-names properties so they
|
||
|
|
also get disabled by the noints override.
