"has-synopsys-hc-bug" is too, although determining whether or not it should apply to a particular controller might be difficult. I'm inclined not to include it among the properties. "no-io-watchdog" is not the greatest name. It describes to controllers that always do generate IRQs for I/O events when they are supposed to (and hence the driver doesn't need to set up a watchdog timer to detect I/O completions that didn't generate an IRQ). So while the concept is HW-specific, the name refers to a driver implementation issue. A better name might be something like "reliable-IRQs". Again, it's not such an easy thing to test for. Almost all the existing drivers leave it unset.
