Hi Greg

Please consider adding

34194cb38503 ("dt-bindings: soc: bcm: Add bcm2712 compatible") 37c3a91e9730 ("arm64: dts: broadcom: bcm2712: Add watchdog DT node") 30ed024fb076 ("mfd: bcm2835-pm: Add support for BCM2712")

to the 6.18.y stable tree. If the bootloader or the ROM code on the RPi5 has enabled the watchdog, the kernel must know about that device in order that either the kernel or userspace can keep petting it.

Strictly, the middle patch is sufficient for that (as the driver matches on the brcm,bcm2835-pm-wdt compatible), but I suppose at least the DT binding patch should go along with it to keep the documentation in sync.

Thanks,
Rasmus

All now queued up, thanks.
