Async interrupt is not a 'card property', but more like a protocol. The intention of this flag is to decide whether to support this feature on SDIO host side. Before that, host need to confirm that async interrupt is supported on card side(by read and parse Support Async Interrupt segment in CCCR from card). > > > > > Signed-off-by: Axe Yang > > --- > > Documentation/devicetree/bindings/mmc/mmc-controller.yaml | 5 > > +++++ > > 1 file changed, 5 insertions(+) > > > > diff --git a/Documentation/devicetree/bindings/mmc/mmc- > > controller.yaml b/Documentation/devicetree/bindings/mmc/mmc- > > controller.yaml > > index 25ac8e200970..7230421583c6 100644 > > --- a/Documentation/devicetree/bindings/mmc/mmc-controller.yaml > > +++ b/Documentation/devicetree/bindings/mmc/mmc-controller.yaml > > @@ -165,6 +165,11 @@ properties: > > description: > > eMMC hardware reset is supported > > > > + cap-sdio-async-int: > > Perhaps be consistent with the next property and use 'irq'.
