Signed-off-by: Guru Das Srinagesh Signed-off-by: Sibi Sankar --- The interrupt property for scm firmware from a binding perspective is completely optional i.e. not all tz fw running in the wild on sm8450 devices support this feature. The bootloader does the interrupt property addition on sm8450 devices with wait-queue support.
