Subject: [PATCH] overlays: gpio-keys: Avoid open-drain warnings
|
|
|
|
The i2c-gpio driver expects to use a GPIO in open-drain mode. Failure
|
|
to configure it in that way causes alarming warnings in the kernel log.
|
|
The BCM283x and BCM2711 GPIO blocks don't support open-drain mode,
|
|
but i2c-gpio works anyway. Silence the warning by declaring that
|
|
open-drain mode has been enabled by other means.
|
|
|
|
