Subject: [PATCH] gpio-fsm: Rename 'num-soft-gpios' to avoid warning
|
||
|
|
|
||
|
|
As of 5.10, the Device Tree parser warns about properties that look
|
||
|
|
like references to "suppliers" of various services. "num-soft-gpios"
|
||
|
|
resembles a declaration of a GPIO called "num-soft", causing the value
|
||
|
|
to be interpreted as a phandle, the owner of which is checked for a
|
||
|
|
"#gpio-cells" property.
|
||
|
|
|
||
|
|
To avoid this warning, rename the gpio-fsm property to "num-swgpios".
