Message-ID <20260705-apple-m4-initial-devicetrees-v1-3-e5655ee56523@cyberchaos.dev>
The watchdog on the Apple silicon t8132 (M4) SoC is compatible with the
existing driver. Add "apple,t8132-wdt" as SoC specific compatible under
"apple,t8103-wdt" used by the driver.

The M4 wdt block additionally has a secondary watchdog, which is
disabled by m1n1 and can safely be ignored by Linux.
