WS1 itself is not optional. The spec says that WS0 and WS1 are separate events, and doesn't saying anything about either being optional. The *interrupt* for WS1, however, is optional.
Besides, what does the driver do with the WS1 interrupt? If it's specified in the device tree, it appears to be ignored by the driver. And the ACPI table only allows for specifying ONE interrupt. So how would the driver register a handler for WS1 on an ACPI system?
