It slipped my mind that https://lore.kernel.org/linux-watchdog/20251231-watchdog-apple-t8103-base-compat-v1-1-1702a02e0c45@jannau.net/ wasn't picked up yet. > > > > > Acked-by: Rob Herring (Arm) > > Reviewed-by: Joshua Peisach > > Reviewed-by: Neal Gompa > > Signed-off-by: Janne Grunau > > --- > > Documentation/devicetree/bindings/watchdog/apple,wdt.yaml | 4 +++- > > 1 file changed, 3 insertions(+), 1 deletion(-) > > > > diff --git a/Documentation/devicetree/bindings/watchdog/apple,wdt.yaml b/Documentation/devicetree/bindings/watchdog/apple,wdt.yaml > > index 05602678c070..845b5e8b5abc 100644 > > --- a/Documentation/devicetree/bindings/watchdog/apple,wdt.yaml > > +++ b/Documentation/devicetree/bindings/watchdog/apple,wdt.yaml > > @@ -16,7 +16,9 @@ properties: > > compatible: > > oneOf: > > - items: > > - - const: apple,t6020-wdt > > + - enum: > > + - apple,t6020-wdt > > + - apple,t8122-wdt > > - const: apple,t8103-wdt > > - items: > > - enum: > > I second Sashiko's findings that the driver will fail to bind because it > only supports "apple,wdt". I would not mind and apply the patch anyway, > but the statement in the description is just plain wrong and thus > misleading. Please fix. I would prefer if the addition of the "apple,t8103-wdt" to the driver is picked. Thanks, Janne
