BCM53573 seems to be the first series of Northstar family with wireless
on the chip. The base models are BCM53573-s (A0, A1) and there is also
BCM47189B0 which seems to be some small modification.

The only problem with these chipsets seems to be watchdog. It's totally
unavailable on 53573A0 / 53573A1 and preferable PMU watchdog is broken
on 53573B0 / 53573B1.

It's been observed that firmware sends RADAR detected event without
specifying bss_num/bss_type. Also, the event body is empty.
Currently the event is being ignored by driver.

"if (le32_to_cpu(rdr_event->passed))" which always fails is also removed.
